General Description

The AT1203 is an ultra-low noise, low dropout voltage,

low quiescent current CMOS LDO, capable of deliver-

ing up to 300mA.

This LDO provides factory preset 1.5V, 1.8V, 1.9V,

2.5V, 2.8V, 3.0V, 3.1V, 3.3V, 4.2V and 5.0V fixed out-

put voltage.

That is ideally suited for input powered（2.5V~5.5V）

from Li-Ion, NiCd, NiMH, Alkaline battery or USB-Base

power system.

Designed with an internal P-channel MOSFET pass

elements maintain ultra-low supply current throughout

the whole entire operating range.

The AT1203 is protected with current limit, ON/OFF

control and thermal shutdown.
