LM1117 www.ti.com SNOS412N–FEBRUARY2000–REVISEDJANUARY2016 7 Detailed Description 7.1 Overview The LM1117 adjustable version develops a 1.25V reference voltage, V , between the output and the adjust REF terminal. As shown in Figure 10, this voltage is applied across resistor R1 to generate a constant current I1. The current I from the adjust terminal could introduce error to the output. But since it is very small (60µA) ADJ compared with the I1 and very constant with line and load changes, the error can be ignored. The constant currentI1thenflowsthroughtheoutputsetresistorR2andsetstheoutputvoltagetothedesiredlevel. Forfixedvoltagedevices,R1andR2areintegratedinsidethedevices. Figure10. BasicAdjustableRegulator 7.2 Functional Block Diagram 7.3 Feature Description 7.3.1 LoadRegulation The LM1117 regulates the voltage that appears between its output and ground pins, or between its output and adjust pins. In some cases, line resistances can introduce errors to the voltage across the load. To obtain the bestloadregulation,afewprecautionsareneeded.

LM1117 SNOS412N–FEBRUARY2000–REVISEDJANUARY2016 www.ti.com Feature Description (continued) Figure 11, shows a typical application using a fixed output regulator. The Rt1 and Rt2 are the line resistances. It is obvious that the V is less than the V by the sum of the voltage drops along the line resistances. In this LOAD OUT case, the load regulation seen at the R would be degraded from the data sheet specification. To improve LOAD this, the load should be tied directly to the output terminal on the positive side and directly tied to the ground terminalonthenegativeside. Figure11. TypicalApplicationUsingFixedOutputRegulator When the adjustable regulator is used (Figure 12), the best performance is obtained with the positive side of the resistorR1tieddirectlytotheoutputterminaloftheregulatorratherthanneartheload.Thiseliminateslinedrops fromappearingeffectivelyinserieswiththereferenceanddegradingregulation.Forexample,a5Vregulatorwith 0.05Ω resistance between the regulator and load will have a load regulation due to line resistance of 0.05Ω x I . L If R1 (=125Ω) is connected near the load, the effective line resistance will be 0.05Ω (1+R2/R1) or in this case, it is 4 times worse. In addition, the ground side of the resistor R2 can be returned near the ground of the load to provideremotegroundsensingandimproveloadregulation. Figure12. BestLoadRegulationUsingAdjustableOutputRegulator 7.4 Device Functional Modes 7.4.1 ProtectionDiodes Under normal operation, the LM1117 regulators 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 signalof±25Vwithrespecttotheoutputvoltagewithoutdamagingthedevice. 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 depends on the value of the capacitor, the output voltage of the regulator, and rate of decrease of V . In the LM1117 regulators, the internal diode between IN the output and input pins can withstand microsecond surge currents of 10A to 20A. With an extremely large outputcapacitor(≥1000 µF),andwithinputinstantaneouslyshortedtoground,theregulatorcouldbedamaged. In this case, an external diode is recommended between the output and input pins to protect the regulator, as showninFigure13. 12 SubmitDocumentationFeedback Copyright©2000–2016,TexasInstrumentsIncorporated ProductFolderLinks:LM1117

LM1117 SNOS412N–FEBRUARY2000–REVISEDJANUARY2016 www.ti.com 8 Application and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 8.1 Application Information The LM1117 is a versatile and high performance linear regulator with a wide temperature range and tight line/load regulation operation. An output capacitor is required to further improve transient response and stability. For the adjustable option, the ADJ pin can also be bypassed to achieve very high ripple-rejection ratios. The LM1117 is versatile in its applications, including its uses as a post regulator for DC/DC converters, battery chargers,andmicroprocessorsupplies. 8.2 Typical Application Figure14. 1.25-Vto10-VAdjustableRegulatorWithImprovedRippleRejection 8.2.1 DesignRequirements The device component count is very minimal, employing two resistors as part of a voltage divider circuit and an output capacitor for load regulation. A 10-μF tantalum on the input is a suitable input capacitor for almost all applications. An optional bypass capacitor across R2 can also be used to improve PSRR. See Recommended OperatingConditionsformoreinformation. 8.2.2 DetailedDesignProcedure The output voltage is set based on the selection of the two resistors, R1 and R2, as shown in Figure 14. For detailsoncapacitorselection,refertoExternalCapacitors. 8.2.2.1 ExternalCapacitors 8.2.2.1.1 InputBypassCapacitor An input capacitor is recommended. A 10-µF tantalum on the input is a suitable input capacitor for almost all applications. 14 SubmitDocumentationFeedback Copyright©2000–2016,TexasInstrumentsIncorporated ProductFolderLinks:LM1117

LM1117 www.ti.com SNOS412N–FEBRUARY2000–REVISEDJANUARY2016 Typical Application (continued) 8.2.2.1.2 AdjustTerminalBypassCapacitor The adjust terminal can be bypassed to ground with a bypass capacitor (C ) to improve ripple rejection. This ADJ bypass capacitor prevents ripple from being amplified as the output voltage is increased. At any ripple frequency, theimpedanceoftheC shouldbelessthanR1topreventtheripplefrombeingamplified: ADJ 1/(2π×f ×C )<R1 (1) RIPPLE ADJ The R1 is the resistor between the output and the adjust pin. Its value is normally in the range of 100-200Ω. For example,withR1=124Ω andf =120Hz,theC shouldbe >11µF. RIPPLE ADJ 8.2.2.1.3 OutputCapacitor The output capacitor is critical in maintaining regulator stability, and must meet the required conditions for both minimum amount of capacitance and equivalent series resistance (ESR). The minimum output capacitance required by the LM1117 is 10 µF, 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 between 0.3 Ω to 22 Ω. In the case of the adjustable regulator, when the C is used, a larger output capacitance (22-µF ADJ tantalum)isrequired. 8.2.3 ApplicationCurve As shown in Figure 15, the dropout voltage will vary with output current and temperature. Care should be taken during design to ensure the dropout voltage requirement is met across the entire operating temperature and outputcurrentrange. Figure15.

LM1117 www.ti.com SNOS412N–FEBRUARY2000–REVISEDJANUARY2016 9 Power Supply Recommendations The input supply to the LM1117 must be kept at a voltage level such that its maximum rating is not exceeded. The minimum dropout voltage must also be met with extra headroom when possible to keep the LM1117 in regulation. An input capacitor is recommended. For more information regarding capacitor selection, refer to ExternalCapacitors. 10 Layout 10.1 Layout Guidelines Some layout guidelines must be followed to ensure proper regulation of the output voltage with minimum noise. Traces carrying the load current must be wide to reduce the amount of parasitic trace inductance and the feedback loop from V to ADJ must be kept as short as possible. To improve PSRR, a bypass capacitor can OUT beplacedattheADJpinandmustbelocatedascloseaspossibletotheIC.IncaseswhenV shortstoground, IN an external diode must be placed from V to V to divert the surge current from the output capacitor and OUT IN protecttheIC.ThediodemustbeplacedclosetothecorrespondingICpinstoincreasetheireffectiveness. 10.1.1 HeatsinkRequirements When 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 summing the individual parts consisting of a series of temperature rises from the semiconductor junction to the operating environment. A one-dimensional steady-state model of conduction heat transfer is demonstrated in Figure 22. 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.
