LP2960 Adjustable Micropower 0.5A Low-Dropout Regulators
April 1999
LP2960
Adjustable Micropower 0.5A Low-Dropout Regulators
General 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 碌A(chǔ) 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 碌F 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 parts are available in 16-pin plastic DIP and 16-pin sur-
face mount packages.
