AME8845

3A CMOS LDO

General Description

The AME8845 family of linear regulators feature low

quiescent current (100µA typ.) with low dropout voltage,

making them ideal for battery applications. It is available

in TO-252, SOT-223, TO-263 and TO-220 packages. The

space-efficient TO-252, SOT-223 package is attractive for

"Pocket" and "Hand Held" applications.

Output voltages are set at the factory and trimmed to

1.5% accuracy.

These rugged devices have both Thermal Shutdown,

and Current Fold-back to prevent device failure under the

"Worst" of operating conditions.

The AME8845 is stable with an output capacitance of

2.2µF or greater.
