LM1117
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 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-
sure output voltage accuracy to within ±1%.
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.
