The LP2960 is a micropower voltage regulator with very low dropout voltage (12 mV typical at 1 mA load and 470 mV typical at 500 mA load) and very low quiescent current (450 μA typical at 1 mA load).

The LP2960 is ideally suited for battery-powered systems: the quiescent current increases only slightly at dropout, which prolongs battery life.

The LP2960 retains all the desirable characteristics of the LP2953, and offers increased output current.

The error flag goes low any time the output drops more than 5% out of regulation.

Reverse battery protection is provided.

The LP2960 requires only 10 μF of output capacitance for stability (5V version).

The internal voltage reference is made available for external use, providing a low-T.C. reference with very good regulation characteristics.

The part is available in a 16-pin surface mount (SOIC) package.
