MIC2950/2951  
150mA Low-Dropout Voltage Regulator  
General Description  
Features  
The MIC2950 and MIC2951 are “bulletproof” micropower  
voltage regulators with very low dropout voltage (typically  
40mV at light loads and 250mV at 100mA), and very low  
quiescent current. Like their predecessors, the LP2950 and  
LP2951, the quiescent current of the MIC2950/MIC2951  
increases only slightly in dropout, thus prolonging battery life.  
The MIC2950/MIC2951 are pin for pin compatible with the  
LP2950/LP2951, but offer lower dropout, lower quiescent  
current,reversebattery,andautomotiveloaddumpprotection.

(reverse battery).

The plastic DIP and SOIC versions offer additional system  
functions such as programmable output voltage and logic  
controlled shutdown. The 3-pin TO-92 MIC2950 is pin-  
compatible with the older 5V regulators.  
These system functions also include an error flag output that  
warns of a low output voltage, which is often due to failing  
batteries on the input. This may also be used as a power-on  
reset. A logic-compatible shutdown input is also available  
which enables the regulator to be switched on and off. This
