1A Low Dropout Positive Voltage Regulator

LM1117L3

Features

Description

●

Adjustable or Fixed Output

Output Current of 1A

The LM1117 series of positive adjustable and fixed

regulators are designed to provide 1A with high

efficiency. All internal circuitry is designed to

operate down to 1.3V input to output differential.

On-chip trimming adjusts the reference voltage to

1%.

Low Dropout, 1.3V max at 1A Output Current

0.04% Line Regulation

0.2% Load Regulation

100% Thermal Limit Burn-in

Fast Transient Response

Applications
