General Description
The AME8807 family of positive, linear regulators fea-
ture low ground current (30µA typ.) with low dropout volt-
age, making them ideal for battery applications. The
space-saving SO-8 package is attractive for "Pocket" and
"Hand Held" applications.
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the
"Worst" of operating conditions.
