LM317
SLVS044X – SEPTEMBER 1997 – REVISED SEPTEMBER 2016
LM317 3-Terminal Adjustable Regulator
1 Features
3 Description

The LM317 device is an adjustable three-terminal
positive-voltage regulator capable of supplying more
than 1.5 A over an output-voltage range of 1.25 V to
37 V. It requires only two external resistors to set the
output voltage. The device features a typical line
regulation of 0.01% and typical load regulation of
0.1%. It includes current limiting, thermal overload
protection, and safe operating area protection.
Overload protection remains functional even if the
ADJUST terminal is disconnected.
