THREE–TERMINAL  
ADJUSTABLE POSITIVE  
VOLTAGE REGULATOR  
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.
