Description

General part information

LM1084 Series

The LM1084 is a regulator with a maximum dropout of 1.5V at 5A of load current. The device has the same pinout as TI’s industry standard LM317.

Two resistors are required to set the output voltage of the adjustable output voltage version of the LM1084. Fixed output voltage versions integrate the adjust resistors.

The LM1084 circuit includes a zener trimmed band-gap reference, current limiting, and thermal shutdown.
