General Description
The AME8808 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-223 and TO-252-2 packages are at-
tractive 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.
The AME8808 is stable with an output capacitance of
2.2µF or greater.
