■Typical Application Circuit

The XC62E series are a group of positive output voltage regulators 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 XC62E is particularly suited for use with battery operated portable

products, and products where supply current regulation is required.

The series comes 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.
