CMOS IC

DESCRIPTION

The UTC UC621XX is a positive output voltage regulator that can

supply up to 1A of output current using an external transistor. Low

power and high accuracy are achieved through CMOS process and

metal fuses trimming technologies.

The series consists of a high precision voltage reference, an error

correction circuit and a short-circuit protected output driver.

In stand-by mode, supply current can be dramatically cut. Since

the input-output voltage differential is small, loss control efficiency is

good.

The UTC UC621XX is particularly suited for use with battery

operated portable products, and products where supply current

regulation is required.
