Description	800-mA Low-Dropout Linear Regulator
Datasheet	LM1117 Datasheet

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.
