General Description
The AME8820 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. The ul-
tra-small CSP package is attractive for "Pocket" and "Hand
Held" applications.
These rugged devices have both Thermal Shutdown,
and Current limit to prevent device failure under the Worst
operating conditions.
The AME8820 is stable with an output capacitance of
1µF or larger.
