RC2951  
Adjustable Micropower Voltage Regulator  
Features  
Description  
• High accuracy output voltage  
The RC2951 is a voltage regulator specifically designed to  
maintain proper regulation with a very low dropout voltage  
(Typ. 40mV at light loads and 380 mV at 100mA). It has a  
low quiescent bias current of 75µA and is capable of supply-  
ing output currents in excess of 100mA. It has internal cur-  
rent and thermal limiting protection. The output can be  
programmed from 1.24V to 29V with two external resistors.  
A fixed output voltage (3.3V) is also available.  
• Guaranteed 100 mA output current  
• Extremely low quiescent current  
• Extremely tight load and line regulation  
• Requires only a 1.0µF output capacitor for stability  
• Internal Current and Thermal Limiting  
• Error flag warns of output dropout  
• Logic-controlled electronic shutdown  
• Output programmable from 1.24 to 29V  
• Fixed 3.3V version available  
The error flag output can be used as power-on reset for  
warning of a low output voltage. The Shutdown input feature  
allows a logic level signal to turn on and off the regulator  
output. The RC2951 is ideally suited for battery powered  
computer, consumer, and industrial equipment where an  
extension of useful battery life is desirable. The RC2951 is  
available in an 8-pin SOIC package.
