ams1117和lm1117区别
ams1117和lm1117区别AMS1117与LM1117只有厂家不同的区别，其他的没有区别。
AMS1117是AMS的产品，输入电压的极限值是15V，LM1117是NS的产品，15V是输入电压的正常上限，极限值是20V，所以后者的耐压值要高一些，但是这类线性稳压器一般适合用于输入输出电压差不太大（3~5V）的场合，否则电流大时效率低发热严重，所以输入电压的极限值高一些用途也不很大。
稳压到3.3V应该选用1117系列产品中后缀为—3.3的信号，如AMS1117—3.3或LM1117—3.3，只要输入电压在工作电压允许范围内，它们的输出电压都是3.3V。
AMS1117系列稳压器有可调版与多种固定电压版，设计用于提供1A输出电流且工作压差可低至1V。
在最大输出电流时，AMS1117器件的压差保证最大不超过1.3V，并随负载电流的减小而逐渐降低。

Transient Response10091911Application Note1.0EXTERNAL CAPACITORS/STABILITY1.1Input Bypass 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/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 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

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 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 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

Cu制程面臨的風險二
高溫焊線過程中，Cu線氧化而帶來焊接缺陷
焊線時，會因放電及熱板加熱時形成CuO，已氧化的FAB (Free Air Ball)球形較不圓，造成焊接缺陷
✓ 防止高溫下Cu線氧化，Bonding機臺采取了改良： 導線機設計在放電結球時吹入Forming Gas (N2:H2=95:5), 防止結球時氧化

鈀銅與純銅的比較
➢ 結論 1.目前供應商所使用的PdCu的成份：Cu -97%左右， Pd-3%左右，很多供 應商在描述PCN時並未具體告知銅線的具體種類，大部份是純銅，少部份是 鈀銅。部份供應商雖然使用鈀銅，但PCN文件仍描述為金線轉銅線，如TI、 Amazing等。 2. 銅線鍍鈀主要目的是防氧化。但成本比較鈀銅較純銅貴。 3. 保護氣體方面：鍍鈀銅線具有只用氮氣就可以的優勢；但純銅線需要氮氫 混合氣體，成本及危險係數比較高； 4. FAB的硬度：鍍鈀銅線相對於純銅線要高，容易造成第一焊點的鋁層擠出 過度以及彈坑現象。這一點可增加鋁墊的厚度來克服這一缺點。 5. 打線參數：第一焊點參數範圍鍍鈀銅線比純銅線要寬，有利於工藝調整。 第二焊點焊接效果鍍鈀銅線要優於純銅線，更加牢固。

I ADJ is 60μA typ. (120μA max.) and ΔI ADJ is 1μA typ. (5μA max.). R1 is normally fixed to 120Ω. From figure 4 we obtain:V OUT =V REF +R2(I ADJ + I R1)=V REF + R2(I ADJ + V REF / R1)=V REF (1+R2/R1) + R2 x I ADJ .Usually R2 value is in the range of few K Ω, so the R2 X I ADJ product could be neglected; then the above expression becomes: V OUT =V REF (1+R2/R1)For better load regulation, realize a good Kelvin connection of R1 and R2 is important. Particularly R1connection must be realized very close to OUT and ADJ pin, while R2 ground connection must be placed as near as possible to the negative Load pin. Ripple rejection can be improved by introducing a 10μF electrolytic capacitor placed in parallel to the R2 resistor (See Fig. 5)V INV OUTFIG.4 Adjustable Output Voltage Application CircuitFIG.5 Adjustable Output Voltage Application with improved Ripple Rejection.TYPICAL PERFORMANCE CHARACTERISTICSR e f e r e n c e V o l t a g e (V )P o w e r (W )UTC assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all UTC products described or contained herein.

I ADJ is 60μA typ. (120μA max.) and ΔI ADJ is 1μA typ. (5μA max.). R1 is normally fixed to 120Ω. From figure 4 we obtain:V OUT =V REF +R2(I ADJ + I R1)=V REF + R2(I ADJ + V REF / R1)=V REF (1+R2/R1) + R2 x I ADJ .Usually R2 value is in the range of few K Ω, so the R2 X I ADJ product could be neglected; then the above expression becomes: V OUT =V REF (1+R2/R1)For better load regulation, realize a good Kelvin connection of R1 and R2 is important. Particularly R1connection must be realized very close to OUT and ADJ pin, while R2 ground connection must be placed as near as possible to the negative Load pin. Ripple rejection can be improved by introducing a 10μF electrolytic capacitor placed in parallel to the R2 resistor (See Fig. 5)V INV OUTFIG.4 Adjustable Output Voltage Application CircuitFIG.5 Adjustable Output Voltage Application with improved Ripple Rejection.TYPICAL PERFORMANCE CHARACTERISTICSR e f e r e n c e V o l t a g e (V )P o w e r (W )UTC assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all UTC products described or contained herein.
