LP2960  
Adjustable Micropower 0.5A Low-Dropout Regulators  
General Description  
Features  
n Output voltage adjusts from 1.23V–29V  
n Guaranteed 500 mA output current  
n 5V and 3.3V versions available  
n 16-pin DIP and 16-pin SO packages  
n Low dropout voltage  
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.  
n Low quiescent current  
n Tight line and load regulation  
n Low temperature coefficient  
n Current limiting and thermal protection  
n Logic-level shutdown  
n Can be wired for snap-ON and snap-OFF  
n Reverse battery protection  
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).  
Applications  
The internal voltage reference is made available for external  
use, providing a low-T.C. reference with very good regulation  
characteristics.  
n High-efficiency linear regulator  
n Regulator with under-voltage shutdown  
n Low dropout battery-powered regulator  
n Cellular telephones  
The parts are available in 16-pin plastic DIP and 16-pin sur-  
face mount packages.
