LM1117/LM1117I

800mA Low-Dropout Linear Regulator

General Description

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.

The LM1117 is available in an adjustable version, which can

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

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

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

The LM1117 offers current limiting and thermal shutdown. Its

circuit includes a zener trimmed bandgap reference to as-

sure output voltage accuracy to within

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.
