LM1117 800mA Low-dropout Linear Regulator

LM1117

8 0 0 mA Low- Dropout Li near Regulator

General Descri pti on

Features

n Available in 2.85V, 3.3V, 5V, and Adjustable Versions

n Space Saving SOT-223 Package

n Current Limiting and Thermal Protection

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.

n Output Current

800mA

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 three fixed

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

The LM1117 offers current limiting and thermal shutdown. Its

circuit includes a zener trimmed bandgap reference to as-

Appli cati ons

n 2.85V Model for SCSI-2 Active Termination

sure output voltage accuracy to within 1%.

n Post Regulator for Switching DC/DC Converter

n High Efficiency Linear Regulators

n Battery Charger

The LM1117 series is available in SOT-223, TO-220, and

TO-252 D-PAK packages. A minimum of 10µF tantalum ca-

pacitor is required at the output to improve the transient re-

sponse and stability.
