General Description

Features

The CP1117 is a series of low dropout three-terminal

Low dropout voltage: 1.2V at 1A output current

regulators with a dropout of 1.2V at 1A output current.

Trimmed current limit

The CP1117 has an adjustable version, that can

On-chip thermal shutdown

provide the output voltage from 1.25V to 12V with only 2

Three-terminal adjustable of fixed 1.5V, 1.8V,

external resistors.

2.5V, 3.3V, 5V

The CP1117 series provides current limiting and

thermal shutdown. Its circuit includes a trimmed bandgap

reference to assure output voltage accuracy to be

within 1%. Current limit is trimmed to ensure specified
