General Description
The AME8801/8840 family of positive, linear regulators
feature low quiescent current (30µA typ.) with low drop-
out voltage, making them ideal for battery applications.
The space-saving SOT-23-5 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 AME8801 is stable with an output capacitance of
2.2µF or greater.
