XC62E Series銆€
Boosting Voltage Regulators
General Description
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 con-
trol efficiency is good.
The XC62E is particularly suited for use with battery operated
portable products, and products where supply current regula-
tion 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 ( cus-
tom ) is also available.
