OUT
The AME8806/8809/8842 family of positive, linear regu-
lators feature low quiescent current (30mA typ.) with low
dropout voltage, making them ideal for battery applica-
tions. The space-saving SO-8 package is attractive for
"Pocket" and "Hand Held" applications.

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

In applications requiring a low noise, regulated supply,
place a 1000 pF capacitor between Bypass and ground.
AMP
The AME8806/8809/8842 is stable with an output ca-
pacitance of 2.2mF or greater.
