450mA ULTRA LOW DROPOUT

POSITIVE VOLTAGE REGULATOR

Description

Features

GM6353 series is a group of positive voltage

output, three-pin regulators, that provide a high

current even when the input/output voltage

differential is small. Low power consumption and

high accuracy is achieved through CMOS and

programmable fuse technologies, with the output

voltage range from 1.5V to 6.0V

Maximum output current up 450mA

Output voltage from 1.5V to 6.0V in

0.1V increments

Output voltage accuracy : ±2%

CMOS low power consumption,

typically

15µA

GM6353 consists of a high precision voltage

reference, an error correction circuit, and a current

limited output driver. Transient response to load

variations has been improved in comparison to

the existing series. The GM6353 incorporates

both over temperature and over current

protection.

Input stability: typically 0.2%/V

Ultra low dropout voltage, 0.1V @ I_OUT

= 100mA
