LM1117/LM1117I

800mA Low-Dropout Linear Regulator

General Description

Features

The LM1117 is a series of low dropout voltage regulators with

a dropout of 1.2V at 800mA of load current. It has the same

pin-out as National Semiconductor's industry standard

LM317.

Available in 1.8V, 2.5V, 2.85V, 3.3V, 5V, and Adjustable

●

The LM1117 is available in an adjustable version, which can

set the output voltage from 1.25V to 13.8V with only two ex-

ternal resistors. In addition, it is also available in five fixed

voltages, 1.8V, 2.5V, 2.85V, 3.3V, and 5V.

Temperature Range

The LM1117 offers current limiting and thermal shutdown. Its

circuit includes a zener trimmed bandgap reference to assure

output voltage accuracy to within ±1%.

The LM1117 series is available in LLP, TO-263, SOT-223,

TO-220, and TO-252 D-PAK packages. A minimum of 10µF

tantalum capacitor is required at the output to improve the

transient response and stability.
