n Functional Block Diagram
l Very Low Dropout Voltage
l Guaranteed 750mA Output
l Accurate to within 1.5%
l 30µA Quiescent Current
l Over-Temperature Shutdown

The AME8843 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 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.
The AME8843 is stable with an output capacitance of
2.2µF or greater.
