■General Description
■Features
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.
Ultra Small Input-Output Voltage Differential
: 100mA of output current is
available with a differential of 0.1V.
(Performance depends on the
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.
