LM341/LM78MXX Series3-Terminal Positive Voltage RegulatorsGeneral DescriptionThe LM341and LM78MXX series of three-terminal positive voltage regulators employ built-in current limiting,thermal shutdown,and safe-operating area protection which makes them virtually immune to damage from output overloads.With adequate heatsinking,they can deliver in excess of 0.5A output current.Typical applications would include local (on-card)regulators which can eliminate the noise and de-graded performance associated with single-point regulation.Featuresn Output current in excess of 0.5A n No

Performance Characteristics(Continued)Design ConsiderationsThe LM78MXX/LM341XX fixed voltage regulator series has built-in thermal overload protection which prevents the de-vice from being damaged due to excessive junction tem-perature.The regulators also contain internal short-circuit protection which limits the maximum output current,and safe-area pro-tection for the pass transistor which reduces the short-circuit current as the voltage across the pass transistor is in-creased.Although the internal power dissipation is automatically lim-ited,the maximum junction temperature of the device must be kept below +125˚C in order to meet data sheet specifica-tions.An adequate heatsink should be provided to assure this limit is not exceeded under worst-case operating condi-tions (maximum input voltage and load current)if reliable performance is to be obtained).1.0Heatsink ConsiderationsWhen an integrated circuit operates with appreciable cur-rent,its junction temperature is elevated.It is important to quantify its thermal limits in order to achieve acceptable per-formance and reliability.This limit is determined by summing the individual parts consisting of a series of temperature rises from the semiconductor junction to the operating envi-ronment.A one-dimension steady-state model of conduction heat transfer is demonstrated in The heat generated at thedevice junction flows through the die to the die attach pad,through the lead frame to the surrounding case material,to the printed circuit board,and eventually to the ambient envi-ronment.Below is a list of variables that may affect the ther-mal resistance and in turn the need for a heatsink.R θJC (Component Variables)R θCA (Application Variables)Leadframe Size &Material Mounting Pad Size,Material,&LocationNo.of

LM78MXX/LM341XX regulators have internal thermal shutdown to protect the device from over-heating.Under all possible operating conditions,the junction temperature of the LM78MXX/LM341XX must be within the range of 0˚C to 125˚C.A heatsink may be required depending on the maxi-mum power dissipation and maximum ambient temperature of the application.To determine if a heatsink is needed,the power dissipated by the regulator,P D ,must be calculated:I IN =I L +I GP D =(V IN −V OUT )I L +V IN I Gshows the voltages and currents which are present in the circuit.The next parameter which must be calculated is the maxi-mum allowable temperature rise,T R (max):θJA =TR (max)/P D If the maximum allowable value for θJA ˚C/w is found to be ≥60˚C/W for TO-220package or ≥92˚C/W for TO-252pack-age,no heatsink is needed since the package alone will dis-sipate enough heat to satisfy these requirements.If the cal-culated value for θJA fall below these limits,a heatsink is required.As a design aid,Table 1shows the value of the θJA of TO-252for different heatsink area.The copper patterns that we used to measure these θJA are shown at the end of the Application Note Section.reflects the same test results as what are in the Table 1shows the maximum allowable power dissipation vs.ambi-ent temperature for theTO-252device.shows the maximum allowable power dissipation vs.copper area (in 2)for

A count enable input serves as the carry/borrowinput in multi-stage counters. Control input, Down/Up, determines whether a circuit counts up or down. A MAX/MIN output and a Ripple Clock output provide overflow/underflow indication and make possible a variety of methods for generating carry/borrow signals in multi-stage counter applications.All inputs are equipped with protection circuits against static discharge and transient excess voltage.M74HC1914 BIT SYNCHRONOUS UP/DOWN COUNTERSPIN CONNECTION AND IEC LOGIC SYMBOLSORDER CODESPACKAGE TUBE T & RDIP M74HC191B1R SOP M74HC191M1RM74HC191RM13TR TSSOPM74HC191TTRM74HC1912/14INPUT AND OUTPUT EQUIVALENT CIRCUITPIN DESCRIPTIONTRUTH TABLEa - d : The level of steady state inputs a through d respectivelyPIN No SYMBOL NAME AND FUNCTION3, 2, 6, 7QA to QDFlip-Flop Outputs 4ENABLECount Enable Input(Active LOW)5U/D Parallel Data Input 11LOAD Load Input (Active LOW)12MA/MI OUT Terminal Count Output13RCRipple Clock Output(Active LOW)14CLOCKClock Input (LOW toHIGH, edge triggered)15, 1, 10, 9DA to DD Data Inputs 8GND Ground (0V)16Vcc Positive Supply VoltageM74HC191 LOGIC DIAGRAM3/14M74HC1914/14TIMING CHARTABSOLUTE MAXIMUM RATINGSAbsolute Maximum Ratings are those values beyond which damage to the device may occur.

of three-terminal positive regulators is available in TO-220,TO-220FP,DPAK and IPAK packages and with several fixed output voltages,making it useful in a wide range of applications.These regulators can provide local on-card regulation,eliminating the distribution problems associated with single point regulation.Each type employs internal current limiting,thermal shut-down and safe area protection,making it essentially indestructible.If adequate heat sinking is provided,they can deliver over 0.5A output current.Although designed primarily as fixed voltage regulators,these devices can beused with external components to obtainadjustable voltage and currents.L78M00SERIESPOSITIVE VOLTAGEREGULATORSL78M00SERIES2/21ABSOLUTE MAXIMUM RATINGSAbsolute Maximum Ratings are those values beyond

Samples for carbon analysis of carbon and alloy steel shall be taken no closer than1⁄4in.[6mm]to a cast surface,except that castings too thin for this shall be analyzed on representative material.The chemical composition thus determined shall meet the requirements speciﬁed in the applicable speciﬁcation for the grade involved,or shall be subject to rejection by the purchaser,except that the chemical composition determined for carbon and low alloy steel castings may vary from the speciﬁed limits by the amounts shown in Table1.The product analysis tolerances of Table1are not applicable as acceptance criteria for heat analysis by the casting manufacturer.When comparing product and heat analysis for other than carbon and low alloy steels,the reproducibility Data R2,in Test Methods E353or E354,as applicable,shall be taken intoconsideration.5.4Unspeciﬁed Elements —When chemical analysis for el-ements not speciﬁed for the grade ordered is desired,Supple-mentary Requirement S13may be speciﬁed.5.4.1Grade substitution,for stainless steel or nickel base alloy castings,is not permitted.Grade substitution occurs when the material supplied:(1)contains an element,other than nitrogen,that is not speciﬁed in the ordered grade;and,(2)the amount of that element equals or exceeds the minimum requirement for the element in another grade for which it is speciﬁed.For this requirement,a grade is deﬁned as an alloy described individually in a table of chemical requirements within any speciﬁcation listed within the scope of A 781/A 781M.6.Mechanical Test Requirements6.1The individual product speciﬁcations vary as to whether mechanical tests are required;for this reason,and to determine speciﬁc test requirements,the individual product speciﬁcation should be reviewed.6.2Unless otherwise speciﬁed by the purchaser,when mechanical properties are required by the product speciﬁca-tion,test coupons may be cast integrally with the castings,or as separate blocks,in accordance with Fig.1,Fig.2,or Fig.3,except when Supplementary Requirement S15is speciﬁed.Thetest coupon in Fig.3shall be employed only for austenitic alloy castings with cross sections less than 21⁄2in.[65mm].37.Workmanship,Finish,and Appearance7.1All castings shall be made in a workmanlike manner and shall conform to the dimensions on drawings furnished by the purchaser before manufacture is started.If the pattern is supplied by the purchaser,the dimensions of the casting shall be as predicated by the pattern.8.Quality8.1The surface of the casting shall be free of adhering sand,scale,cracks,and hot tears as determined by visual examina-tion.Other surface discontinuities shall meet the visual accep-tance standards speciﬁed in the order.Practice A 802/A 802M or other visual standards may be used to deﬁne acceptable surface discontinuities and ﬁnish.Unacceptable visual surface discontinuities shall be removed and their removal veriﬁed by visual examination of the resultant cavities.8.2When additional inspection is desired,Supplementary Requirements S1,S2,S3,S4,or S5may be speciﬁed.8.3Rejectable indications shall not be peened,plugged,or impregnated.9.Repair9.1Repair by welding shall be in accordance with the requirements of the individual speciﬁcation using procedures and welders qualiﬁed in accordance with Practice A 488/A 488M .10.Inspection10.1The manufacturer shall afford the purchaser’s inspector all reasonable facilities necessary to satisfy that the material is being produced and furnished in accordance with the appli-cable speciﬁcation.Foundry inspection by the purchaser shall not interfere unnecessarily with the manufacturer’s operations.All tests and inspections,with the exception of product analysis (5.3),shall be made at the place of manufacture unless otherwise agreed.11.Rejection11.1Subsequent to acceptance at the manufacturer’s works,material that is found to be unacceptable as determined by requirements speciﬁed in the order may be rejected by the purchaser.The manufacturer should be notiﬁed of such rejec-tion.If the manufacturer is dissatisﬁed with the results of any tests performed by the purchaser,he may make claim for a rehearing.12.Keywords12.1castings;common requirements;steel and alloy3Information on the relationship of mechanical properties determined on test coupons obtained as speciﬁed in 6.2with those obtained from the casting may be found in The Steel Casting Handbook ,Fifth Edition,Steel Founders’Society of America,pp.15-35through 15-43,1980.TABLE 1Product Analysis

speciﬁcation are to be inserted into the equation to calculate the tolerance for the upper limit and the lower limit (if applicable),respectively.Examples of computing tolerances are presented in footnote C.CTo illustrate the computation of the tolerance,consider the manganese maximum of 0.70for a 0.30carbon grade 65-35in Speciﬁcation A 27/A 27M .The maximum permissible deviation is (0.0830.70+0.01)=0.066.Therefore,the highest acceptable product analysis is 0.766.Similarly,for a 0.20carbon grade 70-40in Speciﬁcation A 27/A 27M ,the maximum manganese content is 1.40;thus,the highest acceptable product analysis is (1.40+0.09)=1.49.Metric Equivalentsin.[mm]3⁄16[4.8]1⁄2[13]11⁄4[32]13⁄4[45]2[51]21⁄4[57]37⁄8[98]5[127]83⁄8[213]Leg Design [125mm]Riser Design1.L (length)A 5in.[125mm]minimum length will be used.Thislength may be increased at the option of the foundry to accommodate additional test specimens (see Note 1).1.L (length)The length of the riser at the base will be the same as the top length of the leg.The length of the riser at the top therefore depends on the amount of taper added to the riser.2.End TaperUse of and size of end taper is at the option of the foundry.2.WidthThe width of the riser at the base of a multiple-leg cou-pon shall be n (21⁄4)[57mm]-5⁄8[16mm]where n equals the number of legs attached to the coupon.The width of the riser at the top is therefore dependent on the amount of taper added to the riser.3.Height 11⁄4in.[32mm]4.Width (at top)11⁄4[32mm](see Note 1).5.Radius (at bottom)1⁄2in.[13mm],max6.Spacing between legs A

the option of the foundry for the following reasons:(a )many risers are cast open,(b )different compositions may require variation in risering for soundness,and (c )different pouring temperatures may require variation in risering for soundness.7.Location of test speci-mens The tensile,bend,and impact specimens will be taken from the lower portion of the leg (see Note 2).8.Number of legs The number of legs is at the option of the foundry pro-viding they are equi-spaced according to Item 6.9.R s Radius from 0to approximately 1⁄16in.[2mm].N OTE 1—Test Coupons for Large and Heavy Steel Castings:The

agreed upon between the manufacturer and purchaser.S14.Tension Test from CastingsS14.1In addition to the tension test required by the material speciﬁcation,test material shall be cut from the casting.The mechanical properties and location for the test material shall be agreed upon by the manufacturer and purchaser.S15.Alternate Mechanical Test Coupons and SpecimenLocations for Castings S15.1Test coupons may be cast integrally with the castings or separately.Separately cast coupons shall be heat-treated together with the castings they represent.S15.2In the following,the casting thickness,T ,is the maximum thickness of the casting exclusive of padding added for directional solidiﬁcation,ﬂanges,appendages,and sections designated by the designer as noncritical.The order,inquiry,and drawing shall designate what the test dimension,T ,is for the casting.S15.3One of the following shall apply:S15.3.1The longitudinal centerline of the test specimen shall be taken at least ¼T from the T dimension surface and all of the gage length must be at least 1T from any other heat treated surface,exclusive of the surface opposite the T dimen-sion surface.(See Fig.S15.1(a).)For cylindrical castings,the longitudinal centerline of the specimens shall be taken at least ¼T from the outside or inside and all of the gage length must be at least T from the as-heat-treated end.(See Fig.S15.1(b).)For ferritic and martensitic castings,partial severing of test coupons prior to ﬁnal heat treatment ispermitted.Minimum length of the base—Specimen gage length +2xT +2x the thickness due to the tapes.Minimum width of the base—T +2x the thickness added due to the taper.Minimum height —T +NxD +W tot .The taper is to be selected by the producer for ease of drawing the pattern from the mold.where:N =number of specimens to be cut from one side of the coupon,D =diameter of the specimens,andW tot =the total width of metal required to remove the coupon from the casting,and to machine specimens from the coupon.N OTE —Longitudinal axis and gage length of test specimen must be within shaded zone.FIG.S15.1Specimen fromCastingS15.3.2Where separately cast test

production casting it represents.Cen-trifugal castings may be represented by statically cast coupons.(See Fig.S15.2.)S15.3.3When agreed upon by the manufacturer and the purchaser,castings that are cast or machined to essentially the ﬁnished conﬁguration prior to heat-treatment shall have test specimens removed from a prolongation or other stock on the casting at a location below the nearest heat-treated surface indicated on the order.The specimen location shall be at a distance below the nearest heat-treated surface equivalent to at least the greatest distance that the indicated high-tensile-stress surface will be from the nearest heat-treated surface and a minimum of twice this distance from a second heat-treated surface,except that the test specimens shall be no nearer than 3⁄4in.[19mm]to a heat-treated surface and 11⁄2in.[38mm]from a second heat-treated surface.(See Fig.S15.3.)S15.3.4Where specimens are to be removed from the body of quenched and tempered castings,either the requirements of S15.3.1shall be met or a steel thermal buffer pad or thermal insulation or other thermal barriers shall be used during heat-treatment.Steel thermal buffer pads shall be a minimum of T by T by 3T in length and shall be joined to the casting surface by a partial penetration weld completely sealing the buffered surface.Test specimens shall be removed from thecasting in a location adjacent to the center third of the buffer pad.They shall be located at a minimum distance of 1⁄2in.[13mm]from the buffered surface and ¼T from other heat-treated surfaces (see Fig.S15.4).When thermal insulation is used,it shall be applied adjacent to the casting surface where the test specimens are to be removed.The producer shall demonstrate that the cooling rate of the test specimen location is no faster than that of specimens taken by the method described in S15.3.1.S16.Weld Repair ChartsS16.1Major weld repairs shall be documented by means of sketches or
