DESCRIPTION

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.
