LP2950/LP2951 150mA Low Drop Out Voltage Regulators  
PRODUCTDESCRIPTION  
The LP2950 and LP2951 are  
low power voltage regulators. These  
devices are an excellent choice for  
use in battery powered applications  
such as cordless telephone, radio  
control systems, and portable  
computers.  
The LP2950 and LP2951  
feature very low quiescent current  
(75µA Typ.) and very low drop  
output voltage (Typ. 40µV at light  
load and 380mV at 100mA). This  
includes a tight initial tolerance of  
0.5% typ., extremely good load and  
line regulation 0.05% typ. and very  
low output temperature coefficient,  
making the LP2950/LP2951 useful  
as a low power voltage reference.  
Other key additional feature of this  
unregulated input voltage transient of  
-20V below ground (reverse battery).  
switched on and off. The LP2950 is  
offered in 3-pin TO-92 package  
compatible with other  
5
volt  
regulators. The LP2951 is available  
in 8-pin plastic, SOP-8 package.  
The regulator output voltage  
may be pin-strapped for a 5 volt of  
programmed from 1.24 volt to 29  
volts with external pair of resistors.  
Using of as design, processing and  
testing techniques make our LP2950  
and LP2951 superior over similar  
products.  
The error flag output feature is  
used as power-on reset for warn of a  
low output voltage, due to following  
batteries on input. Other feature is  
the logic compatible shutdown input  
which enabled\s the regulator to be
