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 pro-longing battery  
life. The MIC2950/MIC2951 are pin for pin compatible with  
the LP2950/LP2951, but offer lower dropout, lower  
quiescent current, reverse battery, and automotive load  
dump protection.  
• High accuracy 3.3, 4.85, or 5V, guaranteed 150mA  
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 1.5µF for stability  
• Current and thermal limiting  
• Unregulated DC input can withstand –20V reverse  
The key additional features and protection offered include  
higher output current (150mA), positive transient protection  
for up to 60V (load dump), and the ability to survive an  
unregulated input voltage transient of –20V below ground  
(reverse battery).  
battery and +60V positive transients  
MIC2951 Version Only  
• Error flag warns of output dropout  
• Logic-controlled electronic shutdown  
• Output programmable from 1.24 to 29V  
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.  
Applications  
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 part may also be pin-strapped for a 5 V output, or  
programmed from 1.24 V to 29 V with the use of two  
external resistors.  
• Automotive electronics  
• Voltage reference  
• Avionics  
• Cellular telephones  
• Battery powered equipment  
• SMPS post-regulator  
• High efficiency linear power supplies
