AME8806 / 8809 / 8842

General Description

The AME8806/8809/8842 family of positive, linear regu-

lators feature low quiescent current (30µA 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.

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.

The AME8806/8809/8842 is stable with an output ca-

pacitance of 2.2µF or greater.
