The AME8833 family of positive, linear regulators fea-
ture low quiescent current (50
µ
A 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 package is attractive for "Pocket" and
"Hand Held" applications.
AME8834's output voltage can be adjusted with an
external resister divider.
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the
"Worst" of operating conditions.
As an additional feature, the AME8833/8834 is stable
with an output capacitance of just extended 0.22
µ
F or
greater.
