Product Summary

The LM317L is a monolithic integrated circuit in SO-8 and TO-92 packages intended for use as positive adjustable voltage regulators. It is designed to supply until 100 mA of load current with an output voltage adjustable over a 1.2 to 37V range. The nominal output voltage is selected by means of only a resistive divider, making the LM317L exceptionally easy to use and eliminating the stocking of many fixed regulators.

Parametrics

LM317L absolute maximum ratings: (1)VI -VO, Input-Output Differential Voltage: 40 V; (2)Pd, Power Dissipation: Internally Limited; (3)Topr, Operating Junction Temperature Range: 0 to 125℃; (4)Tstg, Storage Temperature Range: -55 to 150 ℃.

Features
