LP2952/LP2952A/LP2953/LP2953A  
Adjustable Micropower Low-Dropout Voltage Regulators  
General Description  
Features  
n Output voltage adjusts from 1.23V to 29V  
n Guaranteed 250 mA output current  
n Extremely low quiescent current  
n Low dropout voltage  
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.  
n Extremely tight line and load regulation  
n Very low temperature coefficient  
n Current and thermal limiting  
n Reverse battery protection  
n 50 mA (typical) output pulldown crowbar  
n 5V and 3.3V versions available  
The LP2952 and LP2953 retain all the desirable characteris-  
tics of the LP2951, but offer increased output current, addi-  
tional features, and an improved shutdown function.  
The internal crowbar pulls the output down quickly when the  
shutdown is activated.  
LP2953 Versions Only  
n Auxiliary comparator included with CMOS/TTL  
compatible output levels. Can be used for fault  
detection, low input line detection, etc.  
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.  
Applications  
n High-efficiency linear regulator  
n Regulator with under-voltage shutdown  
n Low dropout battery-powered regulator  
n Snap-ON/Snap-OFF regulator  
The parts are available in DIP and surface mount packages.
