1.0 A Low−Dropout PositiveFixed and AdjustableVoltage Regulators

The NCP1117 series are low dropout positive voltage regulators thatare capable of providing an output current that is in excess of 1.0 Awith a maximum dropout voltage of 1.2 V at 800 mA overtemperature. This series contains eight fixed output voltages of 1.5 V,1.8 V, 2.0 V, 2.5 V, 2.85 V, 3.3 V, 5.0 V, and 12 V that have nominimum load requirement to maintain regulation. Also included is anadjustable output version that can be programmed from 1.25 V to18.8 V with two external resistors. On chip trimming adjusts thereference/output voltage to within ±1.0% accuracy. Internal protectionfeatures consist of output current limiting, safe operating areacompensation, and thermal shutdown. The NCP1117 series canoperate with up to 20 V input. Devices are available in SOT−223 andDPAK packages.

APPLICATIONS INFORMATION

Introduction

The NCP1117 features a significant reduction in dropoutvoltage along with enhanced output voltage accuracy andtemperature stability when compared to older industrystandard three−terminal adjustable regulators. Thesedevices contain output current limiting, safe operating areacompensation and thermal shutdown protection makingthem designer friendly for powering numerous consumerand industrial products. The NCP1117 series is pincompatible with the older LM317 and its derivative devicetypes.

Output Voltage

Frequency compensation for the regulator is provided bycapacitor Cout and its use is mandatory to ensure outputstability. A minimum capacitance value of 4.7 mF with anequivalent series resistance (ESR) that is within the limits of0.25 W to 2.2 W is required. The capacitor type can beceramic, tantalum, or aluminum electrolytic as long as itmeets the minimum capacitance value and ESR limits overthe circuit’s entire operating temperature range. Highervalues of output capacitance can be used to enhance loopstability and transient response with the additional benefit ofreducing output noise.

InputCin3+The typical application circuits for the fixed andadjustable output regulators are shown in Figures 20 and 21.The adjustable devices are floating voltage regulators. Theydevelop and maintain the nominal 1.25 V reference voltagebetween the output and adjust pins. The reference voltage isprogrammed to a constant current source by resistor R1, andthis current flows through R2 to ground to set the outputvoltage. The programmed current level is usually selected tobe greater than the specified 5.0 mA minimum that isrequired for regulation. Since the adjust pin current, Iadj, issignificantly lower and constant with respect to theprogrammed load current, it generates a small outputvoltage error that can usually be ignored. For the fixedoutput devices R1 and R2 are included within the device andthe ground current Ignd, ranges from 3.0 mA to 5.0 mAdepending upon the output voltage.

ǒǓFigure 21. Adjustable Output Regulator

Input bypass capacitor Cin may be required for regulatorstability if the device is located more than a few inches fromthe power source. This capacitor will reduce the circuit’ssensitivity when powered from a complex source impedanceand significantly enhance the output transient response. Theinput bypass capacitor should be mounted with the shortestpossible track length directly across the regulator’s inputand ground terminals. A 10 mF ceramic or tantalumcapacitor should be adequate for most applications.

The output ripple will increase linearly for fixed andadjustable devices as the ratio of output voltage to thereference voltage increases. For example, with a 12 Vregulator, the output ripple will increase by 12 V/1.25 V or9.6 and the ripple rejection will decrease by 20 log of thisratio or 19.6 dB. The loss of ripple rejection can be restoredto the values shown with the addition of bypass capacitorCadj, shown in Figure 21. The reactance of Cadj at the ripplefrequency must be less than the resistance of R1. The valueof R1 can be selected to provide the minimum required loadcurrent to maintain regulation and is usually in the range of100 W to 200 W.

The minimum required capacitance can be calculatedfrom the above formula. When using the device in anapplication that is powered from the AC line via atransformer and a full wave bridge, the value for Cadj is:

Protection Diodes

The NCP1117 family has two internal low impedancediode paths that normally do not require protection whenused in the typical regulator applications. The first pathconnects between Vout and Vin, and it can withstand a peaksurge current of about 15 A. Normal cycling of Vin cannotgenerate a current surge of this magnitude. Only when Vinis shorted or crowbarred to ground and Cout is greater than50 mF, it becomes possible for device damage to occur.Under these conditions, diode D1 is required to protect thedevice. The second path connects between Cadj and Vout, andit can withstand a peak surge current of about 150 mA.Protection diode D2 is required if the output is shorted orcrowbarred to ground and Cadj is greater than 1.0 mF.

D11N4001InputCin+The second condition is that the ground end of R2 should beconnected directly to the load. This allows true Kelvinsensing where the regulator compensates for the voltagedrop caused by wiring resistance RW −.

This series contains an internal thermal limiting circuitthat is designed to protect the regulator in the event that themaximum junction temperature is exceeded. Whenactivated, typically at 175°C, the regulator output switchesoff and then back on as the die cools. As a result, if the deviceis continuously operated in an overheated condition, theoutput will appear to be oscillating. This feature providesprotection from a catastrophic device failure due toaccidental overheating. It is not intended to be used as asubstitute for proper heatsinking. The maximum devicepower dissipation can be calculated by:

PD+

TJ(max)*TA

RqJA

A combination of protection diodes D1 and D2 may berequired in the event that Vin is shorted to ground and Cadjis greater than 50 mF. The peak current capability stated forthe internal diodes are for a time of 100 ms with a junctiontemperature of 25°C. These values may vary and are to beused as a general guide.

Load Regulation

The NCP1117 series is capable of providing excellentload regulation; but since these are three terminal devices,only partial remote load sensing is possible. There are twoconditions that must be met to achieve the maximumavailable load regulation performance. The first is that thetop side of programming resistor R1 should be connected asclose to the regulator case as practicable. This will minimizethe voltage drop caused by wiring resistance RW + fromappearing in series with reference voltage that is across R1.

The devices are available in surface mount SOT−223 andDPAK packages. Each package has an exposed metal tabthat is specifically designed to reduce the junction to airthermal resistance, RqJA, by utilizing the printed circuitboard copper as a heat dissipater. Figures 18 and 19 showtypical RqJA values that can be obtained from a squarepattern using economical single sided 2.0 ounce copperboard material. The final product thermal limits should betested and quantified in order to insure acceptableperformance and reliability. The actual RqJA can varyconsiderably from the graphs shown. This will be due to anychanges made in the copper aspect ratio of the final layout,adjacent heat sources, and air flow.
