■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 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.

7. The maximum output current value is not a value representing continuous output due to the limitations of the 2AS1213 transistor's power
dissipation.
