DESCRIPTION
The LM1117-N 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 Texas
Instruments' industry standard LM317.
The LM1117-N is available in an adjustable version,
which can set the output voltage from 1.25V to 13.8V
with only two external resistors. In addition, it is also
available in five fixed voltages, 1.8V, 2.5V, 2.85V,
3.3V, and 5V.
The LM1117-N offers current limiting and thermal
shutdown. Its circuit includes a zener trimmed
bandgap reference to assure output voltage accuracy
to within ±1%.
The LM1117-N series is available in WSON, PFM,
SOT-223, TO-220, and TO-263 DDPAK packages. A
minimum of 10µF tantalum capacitor is required at
the output to improve the transient response and
stability.
