General Description

The LMS8117 is a series of low dropout voltage regulators

with a dropout of 1.2V at 1A of load current. It has the same

pin-out as National Semiconductor’s industry standard

LM317.

The LMS8117 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 two fixed

voltages, 1.8V and 3.3V.

The LMS8117 offers current limiting and thermal shutdown.

Its circuit includes a zener trimmed bandgap reference to assure output voltage accuracy to within ±1.

The LMS8117 series is available in SOT-223 and TO-252

D-PAK packages. A minimum of 10µF tantalum capacitor is

required at the output to improve the transient response and

stability.
