3 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 V to 13.8 V

with only two external resistors. In addition, the device

is available in five fixed voltages, 1.8 V, 2.5 V, 3.3 V,

and 5 V.

The LM1117 offers current limiting and thermal

shutdown. The circuit includes a Zener trimmed band-

gap reference to assure output voltage accuracy to

within ±1%.

A minimum of 10-µF tantalum capacitor is required

at the output to improve the transient response and

stability.
