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 adj†For information on tape and reel specifications, including part orientation and tape sizes, please refer to our T ape and Reel Packaging Specifi-cations Brochure, BRD8011/D.*NCV prefix is for automotive and other applications requiring site and control changes.†For information on tape and reel specifications, including part orientation and tape sizes, please refer to our T ape and Reel Packaging Specifi-cations Brochure, BRD8011/D.*NCV prefix is for automotive and other applications requiring site and control changes.117AJ ALYWW17−15ALYWW17−18ALYWW117−2ALYWW17−25ALYWW17285ALYWW17−33ALYWW117−5ALYWW17−12ALYWWALYW 117−A 1SOT−223ST SUFFIXCASE 318HA= Assembly Location L= Wafer LotY= YearWW, W= Work Week MARKING DIAGRAMSDPAKDT SUFFIXCASE 369C23ALYW17−15123ALYW17−18123ALYW117−2123ALYW17−25123ALYW7−285123ALYW17−33123ALYW117−5123ALYW17−12123123123123123123 123123123123Adjustable 1.5 V 1.8 V 2.0 V 2.5 V2.85 V3.3 V 5.0 V12 V Adjustable 1.5 V 1.8 V 2.0 V 2.5 V2.85 V3.3 V 5.0 V12 VST SUFFIX CASE 318H−01ISSUE ONOTES:1.DIMENSIONS ARE IN MILLIMETERS.2.INTERPRET DIMENSIONS AND TOLERANCES PER ASME Y14.5M, 1994.3.DIMENSION E1 DOES NOT INCLUDE INTERLEAD FLASH OR PROTRUSION.
