DESCRIPTION
1
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 laser 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.
