AME8804
300mA CMOS LDO
n General Description
The AME8804 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-26 and SOT-25 packages are attrac-
tive 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.
The SOT-26 version also features a "Power Good" de-
tector, which pulls low when the output is out of regula-
tion.
The AME8804 is stable with an output capacitance of
2.2µF or greater.
