750mA CMOS LDO

AME8844

n General Description

n Functional Block Diagram

(Fixed Versions)

TheAME8844 family of positive, linear regulators fea-

ture low quiescent current (45mA typ.) with low dropout

voltage, making them ideal for battery applications.

OUT

Overcurrent

Shutdown

Output voltages are set at the factory and trimmed to

1.5% accuracy.

Thermal

Shutdown

These rugged devices have both Thermal Shutdown,

and Current Fold-back to prevent device failure under the

"Worst" operating conditions.

x115%

ref

An additional feature is a “PowerGood” detector, which

pulls low when the output is out of regulation.

AMP

The AME8844 is stable with an output capacitance of

4.7mF or greater.
