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 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 includes a Zener trimmed
bandgap 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.
