AME8838
n General Description
The AME8838 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 SC-70-5, SC-70-4 & SOT-23 packages are at-
tractive 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 AME8838 is stable with an output capacitance of
1µF or larger.
