DESCRIPTION  
FEATURES  
The LP2951 series of low power voltage regulators  
have low quiescent current and low dropout voltage.  
The quiescent current increases minimally during  
dropout conditions thereby extending battery life.  
= Guaranteed 150mA current  
= Adjustable output voltage - 1.24V to 29V  
= Accurate 5V or 3.3V output @ 100mA  
= Low dropout voltage - 350-400mV @ 100mA  
= Regulator or reference functions  
= Direct replacement for LP2951C, MIC2951-03,  
AS2951C  
Available in the 8 lead SOIC package, the LP2951 se-  
ries includes features such as shutdown and low out-  
put voltage detect (typically due to low battery condi-  
tions). This function may also be used as a power on  
reset function when triggered by CMOS or TTL inputs.  
The circuit can be used as a fixed voltage 5 volt (3.3  
volt for LP2951CM-3.3) regulator or adjusted between  
1.24 volts and 29 volts using external resistor pairs.  
APPLICATIONS  
= Microcontroller supplies  
= Linear regulators  
= Adjustable Supplies  
= Switching power supplies - post-regulation  
= Portable modems  
= Battery powered systems  
= Cellular telephones  
= Voltage references
