LP2950*/2951  
100mA Low-Dropout Voltage Regulator  
General Description  
Features  
The LP2950 and LP2951 are micropower voltage  
regulators with very low dropout voltage (typically 40mV at  
light loads and 380mV at 100mA), and very low quiescent  
current (75A typical). The quiescent current of the LP2950  
/LP2951 increases only slightly in dropout, thus prolonging  
battery life. This feature, among others, makes the LP2950  
and LP2951 ideally suited for use in battery-powered  
systems.  
High accuracy 5V, guaranteed 100mA output  
Extremely low quiescent current  
Low-dropout voltage  
Extremely tight load and line regulation  
Very low temperature coefficient  
Use as regulator or reference  
Needs only 1µF for stability  
Available in a 3-pin TO-92 package, the LP2950 is pin-  
compatible with the older 5V regulators. Additional system  
functions, such as programmable output voltage and logic-  
controlled shutdown, are available in the 8-pin DIP and 8-  
pin SOIC versions of the LP2951.  
LP2951 Versions Only  
Current and thermal limiting  
Error flag warns of output dropout  
Logic-controlled electronic shutdown  
Output programmable from 1.24 to 29V
