AME8803/8814
300mA CMOS LDO
n General Description
The AME8803 family of positive, linear regulators fea-
ture low quiescent current (30µA typ.) with low dropout
voltage, making them ideal for battery applications. The
space-saving SOT-23-6 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.
An additional feature is a "Power Good" detector, which
pulls low when the output is out of regulation. In appli-
cations requiring a low noise, regulated supply, place a
1000pF capacitor between Bypass and ground.
The AME8803 is stable with an output capacitance of
2.2µF or greater.
