三端可调节输出正电压稳压器LM317T资料
三端可调节输出正电压稳压器LM317是可调节3 端正电压稳压器,在输出电压范围为1.2 伏到37 伏时能够提供超过1.5 安的电流。
此稳压器非常易于使用,只需要两个外部电阻来设置输出电压。
此外还使用内部限流、热关断和安全工作区补偿之基本能防止烧断保险丝。
LM317服务于多种应用场合,包括局部稳压、卡上稳压。
该器件还可以用来制伏一种可编程的输出稳压器,或者,通过在调整点和输出之间接一个固定电阻,LM317可用作一种精密稳流器。
* 输出电流超过1.5A *输出在1.2~37V 之间可调节*内部热过载保护*不随温度变化的内部短路电流限制*输出晶体管安全工作区补偿*对高压应用孚空工作*避免置备多种固定电压使W317 稳压器从零伏起调电路、LM317T应用电路一例(转载)lm317LM317 作为输出电压可变的集成三端稳压块,是一种使用方便、应用广泛的集成稳压块。
317 系列稳压块的型号很多:例如LM317HVH 、W317L 等。
电子爱好者经常用317 稳压块制作输出电压可变的稳压电源。
稳压电源的输出电压可用下式计算,Vo=1.25 (1 +R2/R1 )。
仅仅从公式本身看,R1、R2 的电阻值可以随意设定。
然而作为稳压电源的输出电压计算公式,R1 和R2 的阻值是不能随意设定的。
首先317 稳压块的输出电压变化范围是Vo =1.25V —37V (高输出电压的317 稳压块如LM317HVA 、LM317 HVK 等,其输出电压变化范围是Vo =1.25V —45V ),所以R2/R1 的比值范围只能是0 —28.6 。
其次是317 稳压块都有一个最小稳定工作电流,有的资料称为最小输出电流,也有的资料称为最小泄放电流。
最小稳定工作电流的值一般为1.5mA 。
由于317 稳压块的生产厂家不同、型号不同,其最小稳定工作电流也不相同,但一般不大于5mA 。
当317 稳压块的输出电流小于其最小稳定工作电流时,317 稳压块就不能正常工作。

This is used to set a constant current flow across an external resistor driver, giving an output voltage V OU T of: V OUT = V REF * (1 + R2 / R1) + I ADJ * R2The device is designed to minimize the term I ADJ (100uA max) and to maintain it very constant with line and load charges. Usually, the error term I ADJ *R2 can be neglected. To obtain the previous requirement, all the regulator quiescent current is returned to the output terminal, imposing a minimum load current condition. If the load is insufficient, the output voltage will rise. The GCLM317L is a floating regulator, input-output differential voltage, supplies of very high voltage with respect to ground can be regulated as long as the maximum input-output differential is not exceeded. Furthermore, programmable regulators are easily obtainable and, by connecting a fixed resistor between the adjustment and output, the device can be used as a precision current regulator.Fig 1.

懒惰是很奇怪的东西,它使你以为那是安逸,是休息,是福气;但实际上它所给你的是无聊,是倦怠,是消沉;它剥夺你对前途的希望,割断你和别人之间的友情,使你心胸日渐狭窄,对人生也越来越怀疑。

LM317工作原理:LM317的输入最同电压为30多伏,输出电压1.5----32V...电流1.5A...不过在用的时候要注意功耗问题...注意散热问题。
LM317有三个引脚.一个输入一个输出一个电压调节。
输入引脚输入正电压,输出引脚接负载, 电压调节引脚一个引脚接电阻(200左右)在输出引脚,另一个接可调电阻(几K)接于地.输入和输出引脚对地要接滤波电容.
