LMS8117A
1A Low-Dropout Linear Regulator
General Description
The LMS8117A 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 LMS8117A 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 LMS8117A offers current limiting and thermal shutdown.
Its circuit includes a zener trimmed bandgap reference to
assure output voltage accuracy to within
The LMS8117A 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.
