800 mA Low-Dropout Linear

Regulator

LM1117

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 to

13.8 V with only two external resistors. In addition, it 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. Its

circuit is trimmed to assure output voltage accuracy to within +/−1%.
