AME8822

General Description

The AME8822 family of positive, linear regulators fea-

ture low quiescent current (30µA typ.) low dropout volt-

age and excellent PSRR, thus making them ideal for tele-

communications and other battery applications.

These rugged devices have both thermal shutdown and

current limit to prevent device failure under the "Worst"

operating conditions.

The AME8822 is stable with an output capacitance of

1µF or larger.
