LOW CURRENT  
THREE–TERMINAL  
ADJUSTABLE POSITIVE  
VOLTAGE REGULATOR  
The LM317L is an adjustable 3–terminal positive voltage regulator  
capable of supplying in excess of 100 mA 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 them essentially blow–out proof.  
SEMICONDUCTOR  
TECHNICAL DATA  
The LM317L 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 LM317L can be used as a precision current regulator.
