MC78M00, MC78M00A Series500 mA Positive Voltage RegulatorsThe MC78M00/MC78M00A Series positive voltage regulators are identical to the popular MC7800 Series devices, except that they are specified for only half the output current. Like the MC7800 devices,the MC78M00 three-terminal regulators are intended for local,on-card voltage regulation.Internal current limiting, thermal shutdown circuitry and safe-area compensation for the internal pass transistor combine to make these devices remarkably rugged under most operating conditions.Maximum output current, with adequate heatsinking is 500 mA.Features•ăNo External Components Required •ăInternal Thermal Overload Protection •ăInternal Short Circuit Current Limiting •ăOutput Transistor Safe-Area Compensation •ăMC78M00A High Accuracy (±2%)Available for 5.0 V , 8.0 V , 12 V and 15 V •ăPb-Free Packages are Available*Figure 1.

However, it is recommended that the regulator input be bypassed with a capacitor if theregulator is connected to the power supply filter with long wire lengths, or if the output load capacitance is large. An input bypass capacitor should be selected to provide good high frequency characteristics to insure stable operation under all load conditions. A 0.33 m F or larger tantalum,mylar, or other capacitor having low internal impedance at high frequencies should be chosen. The bypass capacitor should be mounted with the shortest possible leads directly across the regulator's input terminals. Normally good construction techniques should be used to minimize ground loops and lead resistance drops since the regulator has no external sense lead.m FThe MC78M00 series can be current boosted with a PNP transistor. The MJ2955 provides current to 5.0 A. Resistor R in conjunction with the V BE of the PNP determines when the pass transistor begins conducting; this circuit is not short circuit proof. Input-output differential voltage minimum is increased by V BE of the pass transistor.InputThe circuit of Figure 12 can be modified to provide supply protection against short circuits by adding a short circuit sense resistor, R sc ,and an additional PNP transistor. The current sensing PNP must be able to handle the short circuit current of the three-terminal regulator .Therefore, a 4.0 A plastic power transistor is specified.XX = 2 digits of type number indicating voltage.Figure 12.

3.BOARD OPERATION3.1ACF–II Operating ModeAFC–II has four operating modes. Any one of these modes can be selected using the digital code input to MODE 0 and MODE 1 using ROTARY SW. The function of each mode is as follows.(1)Normal fsc ModeThis is the mode for usual Y/C separation. It separates Y/C from the video signal that is input to the A/D converter.The coring parameter of the vertical enhancer can be set up by the digital code that is input to C0 – C3 (block level parameter), C4 – C7 (white level parameter), and D4 – D7 (noise slice level parameter). The clock is a 3.579545 MHz subcarrier input to the CLK connector; the built–in 4x PLL generates 4xfsc clock.(2)Normal 4xfsc ModeThis mode is used for Y/C separation. It separates Y/C from the video signal that is input to the A/D con-verter.The coring parameter of the vertical enhancer can be set up by the digital code that is input to C0 – C3 (block level parameter), C4 – C7 (white level parameter), and D4 – D7 (noise slice level parameter). The clock is 14.31818 MHz which is a 4x subcarrier input to the CLK connector.(3)Digital Input Comb Filter ModeThis mode uses the A/D converter, filter, and D/A converter as two independent blocks. The digital data converted by the A/D converter is output on C0 – C7. Data input on D0 – D7 is processed by the ACF–II. Filtering is performed by the algorithm of ACF–II and the Y/C video is output as analog signals from Y out and C out. These two blocks can operate with input clock signals that have different frequencies or phases and can be operated independently by using the CLK(AD) for the A/D converter, and the CLK input for the D/A converter.The clock is 14.31818 MHz which is a 4x subcarrier input to the CLK connector and the CLK(AD) con-nector.(4)Digital Output Comb Filter ModeIn addition to the normal Y/C analog outputs, the MC141622EVK can provide the Y/C signals as digital luminance and chrominance signals. The digital luminance data is output on C0 – C7 and the digital chrominance data is output on D0 – D7. This digital data can be modified by other digital processing. MC141622EVK MOTOROLA 24.2Clock Generator CompoundingThe clock generator (MC1378P) provides the necessary reference oscillator and phase locks the clock to the color subcarrier by inputting the composite video signal.VC1 adjusts the horizontal VCO to synchronize the output of the burst gate (pin 5 on the MC1378P) with the input video signal. VC2 adjusts the chroma VCO for maximum amplitude output from the clock buffer (pin 1 on the MC14576).VR3 adjusts pull–in of the chroma PLL filter. This is usually fixed to the center position. VR4 selects the dc bias for the clock buffer output and is usually 2.25 V.4.3Video Amplifier AdjustmentOn the video amplifier (MC14577), the gain is adjusted by VR1. This sets the input range (3.0 Vp–p) of the A/D converter in MC141622FU.VR2 is the clamp level adjustment. This adjusts the sync tip clamping of the input video signal to the video amplifier.4.4Outside InterfaceThe outside interface should provide a composite video input signal to BNC1. The MC141622EVK pro-vides Y/C separation and outputs the luminance from BNC2 and the color signal from BNC3. There is an S output connector on this board for easy connection to instruments having an S input connector.BNC4 and BNC5 are for the external input of each CLK and CLK(AD). However, when using these, it is necessary to modify the board pattern; i.e., cut (J5, J6).There is no filter for bandwidth limitations on this board beyond that imposed by the bandwidth limitations of the MC14577 buffer amplifier. To minimize noise resulting from excessive bandwidth, the bandwidth of input video signal should be limited to no more than one half of the clock frequency.MC141622EVK MOTOROLA 4MC141622EVK MOTOROLA66.MC141622EVK PARTS LISTReference Designation Description IC1MC141622FU IC2MC14576CP IC3MC14577CP IC4MC7805CT IC5MC14576CP IC6MC1378P TR12SC2002TR22SC2002TR32SA953R19.1 k ΩR262 k ΩR3, R475 ΩR5 3.6 k ΩR6750 k ΩR7, R8 2.0 k ΩR9510 ΩR10150 ΩR11510 k ΩR12, R13 2.2 k ΩR1447 k Ω x 4R1547 k Ω x 8R1610 k Ω x 8R1747 k Ω x 8R1810 k Ω x 8R19, R2010 k Ω x 4R21200 ΩR22 1.8 k ΩR23680 ΩR24750 k ΩR25 2.2 k ΩR267.5 m ΩR27 1.0 m ΩR28150 ΩR29470 k ΩL1 – L933 µH L10 4.7 µH L1133 µH VR1 1 k ΩVR2 2.2 k ΩVR3 1 k ΩVR4 1 m ΩVC1, VC230 pF SW1, SW2Toggle Switch DIP SW1, DIP SW28 Channel Dip Switch ROTARY SW16 Channel Switch 4 MHz Cer.

Rev. 1.0.1Features•Output Current up to 1A •Output V oltages of 5, 6, 8, 9, 10, 12, 15, 18, 24V•Thermal Overload Protection •Short Circuit Protection•Output Transistor Safe Operating Area ProtectionDescriptionThe MC78XX/LM78XX/MC78XXA series of three terminal positive regulators are available in theTO-220/D-PAK package and with several fixed output voltages, making them useful in a wide range ofapplications. Each type employs internal current limiting,thermal shut down and safe operating area protection,making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current.Although designed primarily as fixed voltage regulators,these devices can be used with external components toobtain adjustable voltages and currents.TO-220D-PAK1.

DEFINITIONS
Dropout Voltage – The input/output voltage differential at which the regulator output no longer maintains regulation against further reductions in input voltage. Measured when the output drops 100 mV below its nominal value (which is measured at 1.0 V differential), dropout voltage is affected by junction temperature, load current and minimum input supply requirements. Line Regulation – The change in output voltage for a change in input voltage. The measurement is made under conditions of low dissipation or by using pulse techniques such that average chip temperature is not significantly affected. Load Regulation – The change in output voltage for a change in load current at constant chip temperature. Maximum Power Dissipation – The maximum total device dissipation for which the regulator will operate within specifications. Supply Current – Current which is used to operate the regulator chip and is not delivered to the load.

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
