Transient Response10091911Application Note1.0External Capacitors/Stability1.1Input Bypass CapacitorAn input capacitor is recommended.A10µF tantalum on theinput 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 theoutput voltage is increased.At any ripple frequency,theimpedance of the C ADJ should be less than R1to prevent theripple 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 output set resistor R2and sets the output voltage to the desired level.For fixed voltage devices,R1and R2are integrated inside the 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/LM1117I9Application 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 pins can 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

Note(Continued)The LM1117regulators have internal thermal shutdown to protect the device from over-heating.Under all possible operating conditions,the junction temperature of the 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 DIf 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 Section.Figure 7and Figure 8reflects the same test results as what are in the Table 1Figure 9and Figure 10shows the maximum allowable power dissipation vs.ambient temperature for the SOT-223and TO-252device.Figures Figure 11and Figure

1117 ADJ电压计算
1117 ADJ电压计算
1117有固定电压输出和可调电压输出两种,比如1117-1.8就是固定电压输出1.8V,而不带后缀的就是可调节电压的。
这个1117不带后缀,是通过ADJ脚加外围电路电阻的比例来确定输出电压的。
先看各个脚分配:
实际的电路如下:
这样的电路,DATASHEET给出了计算输出电压的公式:
VOUT=1.250×(R1+R2)/R1
那我们需要确定R1,R2的值
看实际照片,R1为R47,上面的印刷为36A,好像跟一般的电阻标注不一样。
这个是一种E-96标注方式,需要查表,我反正是不记得,表格如下
可查到R1值为
36代表232,A代表是10的0次方,也就是1,这样R1=232*1=232欧姆
另外一个R2也一样,算出是100欧姆,代入公式
VOUT=1.250*(232+100)/232= 1.7888V。
与实际拿万用表测量数据差不多。
我的路由器也修好了,就是这个1117有问题,一有负载马上电压就降了。
换了一个就OK了。
注:计算公式为忽略了IADJ(一般认为是60uA)这个特别小的电流计算得到,完整公式可自行查看DATASHEET。

TempCURRENT LIMIT AND THERMAL PROTECTION BLOCK DIAGRAMCURRENT LIMIT AND THERMAL PROTECTION DETAILED DESCRIPTIONA1117A is a series of low dropout voltage, three terminal regulators. Its application circuit is very simple: the fixed version only needs two capacitors and the adjustable version only needs two resistors and two capacitors to work. It is composed of some modules including start-up circuit, bias circuit, bandgap, thermal shutdown, current limit, power transistors and its driver circuit and so on.The thermal shut down modules can assure chip and its application system working safety when the junction temperature is larger than 140°C.The bandgap module provides stable reference voltage, whose temperature coefficient is compensated by careful design considerations. The temperature coefficient is under 100ppm/°C. And the accuracy of output voltage is guaranteed by trimming technique.TYPICAL APPLICATIONA1117A has an adjustable version and fixed versions (1.2V, 1.8V, 2.5V, 3.3V and 5V)Fixed Output Voltage VersionApplication circuit of A1117A fixed version1.Recommend using 10uF tan/MLCC capacitor as bypass capacitor (C1) for all application circuit.2.Recommend using 10uF tan/MLCC capacitor to assure circuit stability.Adjustable Output Voltage VersionA1117A-ADJ provides a 1.25V reference voltage. Any output voltage between 1.25V~12V can be achievable by choosing two external resistors (schematic is shown below), R1 and R2CURRENT LIMIT AND THERMAL PROTECTIONApplication Circuit of A1117A-ADJThe output voltage of adjustable version follows the equation: V OUT=1.25 x (1+R2/R1) + I ADJ x R2. We can ignore I ADJ because I ADJ (about 50uA) is much less than the current of R1 (about 2~10mA).1.To meet the minimum load current (>10mA) requirement, R1 is recommended to be 125ohm orlower. As A1117A-ADJ can keep itself stable at load current about 2mA, R1 is not allowed to behigher than 625ohm.ing a bypass capacitor (C ADJ) between the ADJ pin and ground can improve ripple rejection.This bypass capacitor prevents ripple from being amplified as the output voltage is increased. Theimpedance of C ADJ should be less than R1 to prevent ripple from being amplified. As R1 isnormally in the range of 100Ω~500Ω, the value of C ADJ should satisfy this equation: 1/ (2 x f ripple xC ADJ) <R1.THERMAL CONSIDERATIONSWe have to take heat dissipation into great consideration when output current or differential voltage of input and output voltage is large. Because in such cases, the power dissipation consumed by A1117A is very large. A1117A series uses SOT-223 package type and its thermal resistance is about 20°C/W. And the copper area of application board can affect the total thermal resistance. If copper area is 5cm x 5cm (two sides), the resistance is about 30°C/W. So the total thermal resistance is about 20°C/W + 30°C/W. We can decrease total thermal resistance by increasing copper area in application board. When there is no good heat dissipation copper are in PCB, the total thermal resistance will be as high as 120°C/W, then the power dissipation of A1117A could allow on itself is less than 1W. And furthermore, A1117A will work at junction temperature higher than 125°C under such condition and no lifetime is guaranteed.CURRENT LIMIT AND THERMAL PROTECTION PACKAGE INFORMATIONDimension in SOT-223 (Unit: mm)CURRENT LIMIT AND THERMAL PROTECTION Dimension in TO-252 Package (Unit: mm)AiT Semiconductor Inc.

The A1117’s application circuit is very simple: the fixed version only needs two capacitors and the adjustable version only needs two resistors and two capacitors to work. The A1117 is composed of some modules including start-up circuit, bias circuit, band-gap, thermal shutdown, current limit, power transistors and A1117’s driver circuit etc.Thermal Shutdown Thermal ShutdownThe thermal shutdown and current limit modules can assure chip and its application system working safety when the junction temperature is larger than 140o C or output current is larger than 1.4A.Band Band--gap Module gap ModuleThe band-gap module provides stable reference voltage, whose temperature coefficient is compensated by careful design considerations. The temperature coefficient is under 100ppm/o C. And the accuracy of output voltage is guaranteed by trimming technique.Fixed Output Version Fixed Output VersionA1117 has adjustable & fixed output version, Fig 1. is typical Fixed output version application.Fig 1. Fixed Output Voltage Version1. Recommend using 10uF tan capacitor as bypass capacitor(C IN ) for all application circuit.2. Recommend using 22uF tan capacitor to assure circuit stability (C OUT )THERMAL PROTECTION AND 1.4A CURRENT LIMIT Adjustable Output VersionAdjustable Output VersionA1117 has adjustable & fixed output version, Fig 2. is typical adjustable output version application. The A1117 adjustable version provides 1.25V reference voltage. Any output voltage between 1.25V~13.8V can be available by choosing two external resistors (R1 & R2, connection method is showed in Fig 2.)Fig2. Adjustable Output VersionThe output voltage of adjustable version satisfies this followed equation:V OUT=V REF*(1+R2/R1) + I ADJ*R2.We can ignore I ADJ because I ADJ (about 50uA) is much less than the current of R1 (about 4mA).The value of R1 should be I the range of 200Ω~350Ω to assure chip working normally without any load. To assure the electrical performance, the output current should be larger than 5mA. If R1 is too large, the minimum output current should be larger than 4mA. The best working condition is to assure that the output current exceeds 10mA.Using a bypass capacitor (C ADJ) between the adjust terminal and ground can improve ripplerejection, This bypass capacitor prevents ripple from being amplified as the output voltageis increased. The impedance of C ADJ should be less than the resistor’s (R1) which isbetween output and adjust pins to prevent ripple from being amplified at any ripplefrequency. As R1 is normally in the range of 200Ω~350Ω,the value of C ADJ should satisfythis equation:2*F RIPPLE*C ADJ<R1. Recommend using 10uF tan capacitor.THERMAL PROTECTION AND 1.4A CURRENT LIMIT Thermal ConsiderationThermal ConsiderationHeat dissipation should be considered when output current or differential voltage of input and output voltage is large. In such case, the power dissipation consumed by A1117 is very large. The A1117 series uses SOT-223 package type and its thermal resistance is about 0o C/W. And the copper area of application board can affect the total thermal resistance. If copper area is 5cm & 5cm (two sides), the resistance is about 30o C/W. So total thermal resistance is about 20o C/W + 30o C/W. It can be decreased total thermal resistance by increasing copper area in application board.THERMAL PROTECTION AND 1.4A CURRENT LIMITPACKAGE INFORMATIONPACKAGE INFORMATIONDimension in SOT-223 (Unit: mm)Tape Dimension Reel DimensionSymbol Min.
