XC62E Series

ETR0311_003

Boosting Voltage Regulators

■GENERAL DESCRIPTIO N

The XC62E series are a group of positive output voltage regulators that can suppl y 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 c ontrol
efficiency is good.
The XC62E is particularly suited for use with battery operated portable products, and products where supply current
regulation is required.
The series are available in an ultra small SOT-25 package.
In connection with the CE function, apart from the negative logic XC62EP series, a positive logic XC62ER series (custom) is
also available.

■APPLICATIONS

●Portable cameras and video recorders
