LP2952/LP2952A/LP2953/LP2953A

Adjustable Micropower Low-Dropout Voltage Regulators

General Description

The LP2952 and LP2953 are micropower voltage regulators

with very low quiescent current (130 µA typical at 1 mA load)

and very low dropout voltage (typ. 60 mV at light load and

470 mV at 250 mA load current). They are ideally suited for

battery-powered systems. Furthermore, the quiescent cur-

rent increases only slightly at dropout, which prolongs bat-

tery life.

The LP2952 and LP2953 retain all the desirable character-

istics of the LP2951, but offer increased output current,

additional features, and an improved shutdown function.

The internal crowbar pulls the output down quickly when the

shutdown is activated.

The error flag goes low if the output voltage drops out of

regulation.

Reverse battery protection is provided.

The internal voltage reference is made available for external

use, providing a low-T.C. reference with very good line and

load regulation.

The parts are available in DIP and surface mount packages.
