AME8808
750mA CMOS LDO
n General Description
The AME8808 family of positive, linear regulators feature
low quiescent current (30µA typ.) with low dropout volt-
age, making them ideal for battery applications. The
space-saving SOT-223 and DPAK-2 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 AME8808 is stable with an output capacitance of
2.2µF or greater.
