FEATURES
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).

Output Voltage Adjusts from 1.23V–29V
Ensured 500 mA Output Current
5V and 3.3V Versions Available
16-Pin SO Package
The LP2960 is ideally suited for battery-powered
systems: the quiescent current increases only slightly
at dropout, which prolongs battery life.
Low Dropout Voltage
Low Quiescent Current
The LP2960 retains all the desirable characteristics of
the LP2953, and offers increased output current.
Tight Line and Load Regulation
Low Temperature Coefficient
Current Limiting and Thermal Protection
Logic-Level Shutdown
The error flag goes low any time the output drops
more than 5% out of regulation.
Reverse battery protection is provided.
Can be Wired for Snap-ON and Snap-OFF
Reverse Battery Protection
The LP2960 requires only 10 μF of output
capacitance for stability (5V version).
APPLICATIONS
The internal voltage reference is made available for
external use, providing a low-T.C. reference with very
good regulation characteristics.
