LMS8117A - National Semiconductor

LMS8117A 1A Low-Dropout Linear Regulator

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 tw.
