AME8801 / 8812 / 8840

General Description

The AME8801/8812/8840 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 SOT-25/TSOT-25 & SOT-26/TSOT-

26 packages are 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" operating conditions.

In applications requiring a low noise, regulated supply,

place a 1000 pF capacitor between Bypass and Ground.

The AME8801 is stable with an output capacitance of

2.2µF or greater.
