DESCRIPTION  
The UTC M2950/2951 is a monolithic integrated voltage  
regulator with low dropout voltage, and low quiescent current.  
It includes many features that suitable for different  
applications. Available in 3-pin TO-92, DIP-8 and SOP-8  
packages.  
FEATURES  
*High accuracy 2.5, 3.0, 3.3, 3.6 or 5V fixed output for  
TO-92, SOP-8 package.  
*Extremely low quiescent current and dropout voltage.  
*Extremely tight load and line regulation.  
*Current and thermal limiting.  
*Very low temperature coefficient.  
*Logic controlled shutdown and error flag available for DIP  
and SOP package.  
*Output voltage programmable for DIP and SOP package.  
APPLICATIONS  
*Battery powered equipment.  
*High efficient linear regulator down to 1.24V.  
*Cellular phones.
