CP1117

Low Dropout Linear Regulator

General Description

Features

The CP1117 is a series of low dropout three-terminal

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

The CP1117 has an adjustable version, that can

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

external resistors.

z Low dropout voltage: 1.2V at 1A output current

z Trimmed current limit

z On-chip thermal shutdown

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

2.5V, 3.3V, 5V

z Operation junction temp.: 0℃ to 125℃

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

output current and controlled short-circuit current.

Onchip thermal shutdown provides protection against any

combination of overload and ambient temperature that

would create excessive junction temperature.

The CP1117 eries is available in the industry

standard SOT-223 power package
