LM1117I - 800-mA Low-Dropout Linear Regulator

Download the LM1117I datasheet PDF. This datasheet also covers the LM1117 variant, as both devices belong to the same 800-ma low-dropout linear regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM1117 is a low dropout voltage regulator with a dropout of 1.2 V at 800 mA of load current.

The LM1117 is available in an adjustable version, which can set the output voltage from 1.25 to 13.8 V with only two external resistors.

Key Features
