AME8807
n General Description
n Functional Block Diagram
TheAME8807 family of positive, linear regulators fea-
ture low ground current (30mA Typ.) with low dropout volt-
age, making them ideal for battery applications. The
space-savingSOP-8&DFN-8 (3mmx3mmx0.75mm) pack-
ages are attractive for "Pocket" and "Hand Held" applica-
tions.

Shutdown
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the
"Worst" operating conditions.
