1.5A Adjustable Three-terminal Positive Voltage Regulator

LM317C Adjustable Three-Terminal Regulator

3 Features

1 Introduction

The LM317C is a three terminal positive voltage

regulator with maximum 1.5A current output and

adjustable output. The voltage regulator is very easy

to use, which only needs two external resistors to set

the output voltage, and the output voltage can be set

in the range of 1.25V to 37V. In addition, the LM317C

is also designed to integrate internal current limiting,

thermal shutdown and safe working area

compensation, which makes it relatively difficult to

damage and basically prevent the burning of circuit

fuses.

•

The output current exceeds 1.5A

The output is adjustable from 1.25V to

37 V

•

Internal thermal overload protection

Temperature independent internal short

circuit current limit

•

Output transistor safe working area

compensation

Commonly used TO-252 package, as

well as other forms of three pin package

Avoid preparing multiple fixed voltages

The LM317C serves a variety of applications,

including local voltage stabilization and card voltage

stabilization. It can also be used to make a

programmable voltage regulator, or as a precision

current regulator by connecting a fixed resistance

between the adjustment point and the output.
