The device is available in1.5-V,1.8-V,2.5-V,3.3-V,5-V,and adjustable-output voltage options.All internal circuitry is designed to operate down to1-V input-to-output differential.Dropout voltage is specified at a maximum of1.3V at800mA,decreasing at lower load currents.The low-profile surface-mount KTP package allows the device to be used in applications where space is limited. The TLV1117is designed to be stable with tantalum and aluminum electrolytic output capacitors having an ESR between0.2Ωand10Ω.Unlike pnp-type regulators,in which up to10%of the output current is wasted as quiescent current,the quiescent current of the TLV1117flows into the load,increasing efficiency.The TLV1117C device is characterized for operation over the virtual junction temperature range of0°C to125°C, and the TLV1117I device is characterized for operation over the virtual junction temperature range of–40°C to 125°C.Please be aware that an important notice concerning

在应用时，通常与外接电容、限流电阻、滤波电容等元件配合使用，以提高性能。

需要注意的是，在使用过程中，该芯片需要防止强烈的震动、冲击、高温和过高的湿度。

同时，为了安全起见，建议在输出端接上适当的去耦电容。

CapacitorAn input capacitor is recommended.A10µF tantalum on the input is a suitable input bypassing for almost all applications.1.2Adjust Terminal Bypass CapacitorThe adjust terminal can be bypassed to ground with a by-pass capacitor(C ADJ)to improve ripple rejection.This by-pass capacitor prevents ripple from being amplified as the output voltage is increased.At any ripple frequency,the impedance of the C ADJ should be less than R1to prevent the ripple from being amplified:1/(2π*f RIPPLE*C ADJ)<R1The R1is the resistor between the output and the adjust pin. Its value is normally in the range of100-200Ω.For example, with R1=124Ωand f RIPPLE=120Hz,the C ADJ should be> 11µF.1.3Output CapacitorThe output capacitor is critical in maintaining regulator sta-bility,and must meet the required conditions for both mini-mum amount of capacitance and ESR(Equivalent Series Resistance).The minimum output capacitance required by the LM1117is10µF,if a tantalum capacitor is used.Any increase of the output capacitance will merely improve the loop stability and transient response.The ESR of the output capacitor should range between0.3Ω-22Ω.In the case of the adjustable regulator,when the C ADJ is used,a larger output capacitance(22µf tantalum)is required.2.0OUTPUT VOLTAGEThe LM1117adjustable version develops a1.25V reference voltage,V REF,between the output and the adjust terminal. As shown in Figure1,this voltage is applied across resistor R1to generate a constant current I1.The current I ADJ from the adjust terminal could introduce error to the output.But since it is very small(60µA)compared with the I1and very constant with line and load changes,the error can be ig-nored.The constant current I1then flows through the outputset resistor R2and sets the output voltage to the desiredlevel.For fixed voltage devices,R1and R2are integrated insidethe devices.3.0LOAD REGULATIONThe LM1117regulates the voltage that appears between itsoutput and ground pins,or between its output and adjustpins.In some cases,line resistances can introduce errors tothe voltage across the load.To obtain the best load regula-tion,a few precautions are needed.Figure2,shows a typical application using a fixed outputregulator.The Rt1and Rt2are the line resistances.It isobvious that the V LOAD is less than the V OUT by the sum ofthe voltage drops along the line resistances.In this case,theload regulation seen at the R LOAD would be degraded fromthe data sheet specification.To improve this,the load shouldbe tied directly to the output terminal on the positive side anddirectly tied to the ground terminal on the negative side.10091917FIGURE1.Basic Adjustable RegulatorLM1117/LM1117I9ww w.Ch in ad z.C om Application Note(Continued)When the adjustable regulator is used (Figure 3),the best performance is obtained with the positive side of the resistor R1tied directly to the output terminal of the regulator rather than near the load.This eliminates line drops from appearing effectively in series with the reference and degrading regu-lation.For example,a 5V regulator with 0.05Ωresistance between the regulator and load will have a load regulation due to line resistance of 0.05Ωx I L .If R1(=125Ω)is con-nected near the load,the effective line resistance will be 0.05Ω(1+R2/R1)or in this case,it is 4times worse.In addition,the ground side of the resistor R2can be returned near the ground of the load to provide remote ground sens-ing and improve load regulation.4.0PROTECTION DIODESUnder normal operation,the LM1117regulators do not need any protection diode.With the adjustable device,the internal resistance between the adjust and output terminals limits the current.No diode is needed to divert the current around the regulator even with capacitor on the adjust terminal.The adjust pin can take a transient signal of ±25V with respect to the output voltage without damaging the device.When a output capacitor is connected to a regulator and the input is shorted to ground,the output capacitor will discharge into the output of the regulator.The discharge current de-pends on the value of the capacitor,the output voltage of the regulator,and rate of decrease of V IN .In the LM1117regu-lators,the internal diode between the output and input pinscan withstand microsecond surge currents of 10A to 20A.With an extremely large output capacitor (≥1000µF),and with input instantaneously shorted to ground,the regulator could be damaged.In this case,an external diode is recommended between the output and input pins to protect the regulator,as shown in Figure 4.5.0HEATSINK REQUIREMENTSWhen an integrated circuit operates with an appreciable current,its junction temperature is elevated.It is important to quantify its thermal limits in order to achieve acceptable performance and reliability.This limit is determined by sum-ming the individual parts consisting of a series of tempera-ture rises from the semiconductor junction to the operating environment.A one-dimensional steady-state model of con-duction heat transfer is demonstrated in Figure 5.The heat generated at the device 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 environment.Below is a list of variables that may affect the thermal resistance and in turn the need for a heatsink.R θJC (ComponentVariables)R θCA (ApplicationVariables)Leadframe Size &Material Mounting Pad Size,Material,&Location No.of Conduction Pins Placement of Mounting PadDie SizePCB

LM1117must be within the range of 0˚C to 125˚C.A heatsink may be required depending on the maximum power dissipation and maximum ambient temperature of the application.To deter-mine 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 GFigure 6shows 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):T R (max)=T J (max)-T A (max)where T J (max)is the maximum allowable junction tempera-ture (125˚C),and T A (max)is the maximum ambient tem-perature which will be encountered in the application.Using the calculated values for T R (max)and P D ,the maxi-mum allowable value for the junction-to-ambient thermal resistance (θJA )can be calculated:θJA =T R (max)/P D If the maximum allowable value for θJA is found to be ≥136˚C/W for SOT-223package or ≥79˚C/W for TO-220package or ≥92˚C/W for TO-252package,no heatsink is needed since the package alone will dissipate enough heat to satisfy these requirements.If the calculated value for θJA falls below these limits,a heatsink is required.As a design aid,Table 1shows the value of the θJA of SOT-223and TO-252for different heatsink area.The copper patterns that we used to measure these θJA s are shown at the end of the Application Notes

These devices contain output current limiting, safe operating area compensation and thermal shutdown protection making them designer friendly for powering numerous consumer and industrial products. The NCP1117 series is pin compatible with the older LM317 and its derivative device types.Output VoltageThe typical application circuits for the fixed and adjustable output regulators are shown in Figures 20 and 21.The adjustable devices are floating voltage regulators. They develop and maintain the nominal 1.25 V reference voltage between the output and adjust pins. The reference voltage is programmed to a constant current source by resistor R1, and this current flows through R2 to ground to set the output voltage. The programmed current level is usually selected to be greater than the specified 5.0 mA minimum that is required for regulation. Since the adjust pin current, I adj , is significantly lower and constant with respect to the programmed load current, it generates a small output voltage error that can usually be ignored. For the fixed output devices R1 and R2 are included within the device and the ground current I gnd , ranges from 3.0 mA to 5.0 mA depending upon the output voltage.External CapacitorsInput bypass capacitor C in may be required for regulator stability if the device is located more than a few inches from the power source. This capacitor will reduce the circuit’s sensitivity when powered from a complex source impedance and significantly enhance the output transient response. The input bypass capacitor should be mounted with the shortest possible track length directly across the regulator’s input and ground terminals. A 10 m F ceramic or tantalum capacitor should be adequate for most applications.Figure 20. Fixed Output RegulatorFrequency compensation for the regulator is provided by capacitor C out and its use is mandatory to ensure output stability. A minimum capacitance value of 4.7 m F with an equivalent series resistance (ESR) that is within the limits of 0.25 W to 2.2 W is required. The capacitor type can be ceramic, tantalum, or aluminum electrolytic as long as it meets the minimum capacitance value and ESR limits over the circuit’s entire operating temperature range. Higher values of output capacitance can be used to enhance loop stability and transient response with the additional benefit of reducing output noise.Figure 21. Adjustable Output RegulatorV out +V ref ǒ1)R2R1Ǔ)I adj R2The output ripple will increase linearly for fixed and adjustable devices as the ratio of output voltage to the reference voltage increases. For example, with a 12 V regulator, the output ripple will increase by 12 V/1.25 V or 9.6 and the ripple rejection will decrease by 20 log of this ratio or 19.6 dB. The loss of ripple rejection can be restored to the values shown with the addition of bypass capacitor C adj , shown in Figure 21. The reactance of C adj at the ripple frequency must be less than the resistance of R1. The value of R1 can be selected to provide the minimum required load current to maintain regulation and is usually in the range of 100 W to 200 W .C adj u12p f ripple R1The minimum required capacitance can be calculated from the above formula. When using the device in an application that is powered from the AC line via a transformer and a full wave bridge, the value for C adj is:f ripple +120Hz,R1+120W ,then C adj u 11.1m FThe value for C adj is significantly reduced in applications where the input ripple frequency is high. If used as a post regulator in a switching converter under the following conditions:f ripple +50kHz,R1+120W ,then C adj u 0.027m FFigures 10 and 11 shows the level of ripple rejection that is obtainable with the adjust pin properly bypassed.Protection DiodesThe NCP1117 family has two internal low impedance diode paths that normally do not require protection when used in the typical regulator applications. The first path connects between V out and V in , and it can withstand a peak surge current of about 15 A. Normal cycling of V in cannot generate a current surge of this magnitude. Only when V in is shorted or crowbarred to ground and C out is greater than 50 m F, it becomes possible for device damage to occur.Under these conditions, diode D1 is required to protect the device. The second path connects between C adj and V out , and it can withstand a peak surge current of about 150 mA.Protection diode D2 is required if the output is shorted or crowbarred to ground and C adj is greater than 1.0 m F.Figure 22. Protection Diode PlacementD1A combination of protection diodes D1 and D2 may be required in the event that V in is shorted to ground and C adj is greater than 50 m F. The peak current capability stated for the internal diodes are for a time of 100 m s with a junction temperature of 25°C. These values may vary and are to be used as a general guide.Load RegulationThe NCP1117 series is capable of providing excellent load regulation; but since these are three terminal devices,only partial remote load sensing is possible. There are two conditions that must be met to achieve the maximum available load regulation performance. The first is that the top side of programming resistor R1 should be connected as close to the regulator case as practicable. This will minimize the voltage drop caused by wiring resistance RW + from appearing in series with reference voltage that is across R1.The second condition is that the ground end of R2 should be connected directly to the load. This allows true Kelvin sensing where the regulator compensates for the voltage drop caused by wiring resistance RW −.Figure 23. Load SensingRemote LoadThermal ConsiderationsThis series contains an internal thermal limiting circuit that is designed to protect the regulator in the event that the maximum junction temperature is exceeded. When activated, typically at 175°C, the regulator output switches off and then back on as the die cools. As a result, if the device is continuously operated in an overheated condition, the output will appear to be oscillating. This feature provides protection from a catastrophic device failure due to accidental overheating. It is not intended to be used as a substitute for proper heatsinking. The maximum device power dissipation can be calculated by:P D +T J(max)*T AR q JAThe devices are available in surface mount SOT−223 and DPAK packages. Each package has an exposed metal tab that is specifically designed to reduce the junction to air thermal resistance, R q JA , by utilizing the printed circuit board copper as a heat dissipater. Figures 18 and 19 show typical R q JA values that can be obtained from a square pattern using economical single sided 2.0 ounce copper board material. The final product thermal limits should be tested and quantified in order to insure acceptable performance and reliability. The actual R q JA can vary considerably from the graphs shown. This will be due to any changes made in the copper aspect ratio of the final layout,adjacent heat sources, and air flow.Figure 24. Constant Current Regulator Figure 25. Slow Turn−On RegulatorFigure 28. Battery Backed−Up Power SupplyFigure 29. Adjusting Output of FixedVoltage RegulatorsThe 50 W resistor that is in series with the ground pin of the upper regulator level shifts its output 300 mV higher than the lower regulator. This keeps the lower regulator off until the input source is removed.Constant CurrentI out +Vref R)I adjNCP1117DTA AdjustableDPAK 75 Units / Rail NCP1117DTAG DPAK (Pb−Free)NCP1117DTARK DPAK 2500 /
