Description

General part information

LM317L Series

The LM217, LM317 are monolithic integrated circuits in TO-220, TO-220FP, D²PAK and SOT223 packages intended for use as positive adjustable voltage regulators.

They are designed to supply more than 1.5 A of load current with an output voltage adjustable over a 1.2 to 37 V range.

The nominal output voltage is selected by means of a resistive divider, making the device exceptionally easy to use and eliminating the stocking of many fixed regulators.
