LM317描述：
LM317的是一个可调的3端子正电压调节器能够在输出电压范围内提供超过1.5 A的1.2 V至37 V.
该电压调节器是非常容易使用和只需要两个外部电阻来设定输出电压。此外，它采用内部电流限制，
热关断和安全区补偿，使得它本质上吹出的证明。 
LM317供应品种繁多的应用，包括本地，上卡规。此装置也可用于使可编程输出调节器
或连接之间的一个固定电阻调整和输出时， LM317可以用作精密电流调节器。

The LM317 is an adjustable 3−terminal positive voltage regulator

capable of supplying in excess of 1.5 A over an output voltage range of

1.2 V to 37 V. This voltage regulator is exceptionally easy to use and

requires only two external resistors to set the output voltage. Further, it

employs internal current limiting, thermal shutdown and safe area

compensation, making it essentially blow−out proof.

The LM317 serves a wide variety of applications including local, on

card regulation. This device can also be used to make a programmable

output regulator, or by connecting a fixed resistor between the

adjustment and output, the LM317 can be used as a precision current

regulator.
