LM317L

100 mA Adjustable Output,

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.

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.
