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.
