三端稳压集成电路(介绍)
一、简介常见的三端固定集成稳压电路有正电压输出的78××系列和负电压输出的79××系列。
所谓三端就是该集成稳压电路的引出脚只有三条，即：输入端、输出端和接地端；其封装形式采用晶体三极管的标准封装，外形与晶体三极管一样。
因此，用它来组成稳压电源需要的外围元件很少，电路非常简单。
该集成稳压电路内部还设置了过流、芯片过热及调整管安全工作区的保护电路，使用起来安全、可靠。
该系列集成稳压电路型号中的78或79后面的数字代表该三端集成稳压电路的输出电压数值，以伏特（V）为单位。
例如7806表示输出电压为正6V；7924表示输出电压为负24V。
此外，我们还可以发现在数字78××或79××的前面和后面还有一些英文字母，如LM78××、CW78××C、TA78××AP等。
前面的字母称为“前缀”，通常为生产厂家（公司）的代号，如“TA”表示日本东芝公司的产品。
后面的字母称为“后缀”，用来表示输出电压容差和封装形式等。
通常不同生产厂家（公司）对三端集成稳压电路型号后缀所用字母的含义和定义各不相同。
不过，这对我们实际使用影响不大。
78××系列集成稳压电路的输出电压大致有8种（输出电压的种类随厂商的不同而异）： 7805、78 06、7809、7810、7812、7815、7818、7824。
按其最大输出电流又可分为78××、78M××、78××三个分系列。
其中78L××系列的最大输出电流为100mA；78M××系列最大输出电流为500mA；78××系列最大输出电流为1.5A。
78××系列集成稳压电路的外形有多种，详见图1。
其中78L××系列有两种封装形式：一种是金属壳的TO-39封装，见图1（a）；另一种是塑料TO-92封装，见图1（b）。

7812中文资料
7812 中文资料三端稳压集成电路使用时要求输入电压比输出电压值至少大2V以上，即|U1|—｜U2｜>=2V，但也不宜过大。
另外还有自地端流过的静态电流IQ=8mA。
W7812为三端固定正12V输入的集成稳压器,7812引脚图如下图所示。
7812主要参数有：输出直流电压U0＝＋12V,输出电流L:0.1A，M：0。
5A，电压调整率10mV/V，输出电阻R0＝0。
15Ω，输入电压UI的范围15~17V 。
因为一般UI要比U0大3～5V ，才能保证集成稳压器工作在线性区。

滤波电容C1、C2一般选取几百～几千微法.当稳压器距离整流滤波电路比较远时，在输入端必须接入电容器C3（数值为0.33μF ）,以抵消线路的电感效应，防止产生自激振荡。

Pulse testing with low duty cycle is used.a Minimum load current for regulation is 5 mA.6 Application information6.1 Design considerationThe L78 Series of fixed voltage regulators are designed with thermal overload protectionthat shuts down the circuit when subjected to an excessive power overload condition,internal short-circuit protection that limits the maximum current the circuit will pass, andoutput transistor safe-area compensation that reduces the output short-circuit current asthe voltage across the pass transistor is increased. In many low current applications,compensation capacitors are not required. However, it is recommended that the regulatorinput be bypassed with capacitor if the regulator is connected to the power supply filter withlong lengths, or if the output load capacitance is large. An input bypass capacitor should beselected to provide good high frequency characteristics to insure stable operation under allload conditions. A 0.33 µF or larger tantalum, mylar or other capacitor having low internalimpedance at high frequencies should be chosen. The bypass capacitor should bemounted with the shortest possible leads directly across the regulators input terminals.Normally good construction techniques should be used to minimize ground loops and leadresistance drops since the regulator has no external sense lead.The addition of an operational amplifier allows adjustment to higher or intermediate valueswhile retaining regulation characteristics. The minimum voltage obtained with thearrangement is 2 V greater than the regulator voltage.The circuit of Figure 13: "High current voltage regulator" can be modified to provide supplyprotection against short circuit by adding a short circuit sense resistor, RSC, and anadditional PNP transistor. The current sensing PNP must be able to handle the short circuitcurrent of the three terminal regulator Therefore a four ampere plastic power transistor isspecified.1. Although no output capacitor is need for stability, it does improve transient response.2. Required if regulator is located an appreciable distance from power supply filter.Figure 14: High output current with short circuit protectionFigure 16: Split power supply (± 15 V - 1 A)* Against potential latch-up problems.Figure 21: High input and output voltageFigure 22: Reducing power dissipation with dropping resistorThe circuit performs well up to 100 kHz.Figure 25: Adjustable output voltage with temperature compensationQ2 is connected as a diode in order to compensate the variation of the Q1 V BE with the temperature. C allows a slow rise time of the V O.Figure 26: Light controllers (VO(min) = VXX + VBE)Application with high capacitance loads and an output voltage greater than 6 volts need an external diode (see Figure 22: "Reducing power dissipation with dropping resistor") to protect the device against input short circuit. In this case the input voltage falls rapidly while the output voltage decrease slowly. The capacitance discharges by means of the base-emitter junction of the series pass transistor in the regulator. If the energy is sufficiently high, the transistor may be destroyed. The external diode by-passes the current from the IC to ground.7 Typical performance8 Package informationIn order to meet environmental requirements, ST offers these devices in different grades ofECOPACK® packages, depending on their level of environmental compliance.

LM7815详细中文资料
LM7815中文资料目录1.lm7815介绍2.实际应用3.引脚序号、引脚功能4.lm7815应用电路5.7815电参数三端稳压集成电路lm7815。
电子产品中，常见的三端稳压集成电路有正电压输出的lm78 ×× 系列和负电压输出的lm79××系列。
顾名思义，三端IC是指这种稳压用的集成电路，只有三条引脚输出，分别是输入端、接地端和输出端。
它的样子象是普通的三极管，TO- 220 的标准封装，也有lm9013样子的TO-92封装。
1.lm7815介绍用lm78/lm79系列三端稳压IC来组成稳压电源所需的外围元件极少，电路内部还有过流、过热及调整管的保护电路，使用起来可靠、方便，而且价格便宜。
该系列集成稳压IC型号中的lm78或lm79后面的数字代表该三端集成稳压电路的输出电压，如lm7806表示输出电压为正6V，lm7909表示输出电压为负9V。
因为三端固定集成稳压电路的使用方便，电子制作中经常采用。
最大输出电流1.5A，LM78XX系列输出电压分别为5V;6V;8V;9V;10V;12V;15V;18V;24V。
2.实际应用在实际应用中，应在三端集成稳压电路上安装足够大的散热器（当然小功率7815IC内部电路图.的条件下不用）。
当稳压管温度过高时，稳压性能将变差，甚至损坏。
当制作中需要一个能输出1.5A以上电流的稳压电源，通常采用几块三端稳压电路并联起来，使其最大输出电流为N个1.5A，但应用时需注意：并联使用的集成稳压电路应采用同一厂家、同一批号的产品，以保证参数的一致。
另外在输出电流上留有一定的余量，以避免个别集成稳压电路失效时导致其他电路的连锁烧毁。
在lm78 ** 、lm79 ** 系列三端稳压器中最常应用的是TO-220 和TO-202 两种封装。
这两种封装的图形以及引脚序号、引脚功能如附图所示。
图中的引脚号标注方法是按照引脚电位从高到底的顺序标注的。
