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.
