MIC2937A/29371/29372  
750mA Low-Dropout Voltage Regulator  
General Description  
Features  
High output voltage accuracy  
The MIC2937Afamily are “bulletproof” efficient voltage regu-  
lators with very low dropout voltage (typically 40mV at light  
loads and 300mV at 500mA), and very low quiescent current  
(160µA typical). The quiescent current of the MIC2937A in-  
creases only slightly in dropout, thus prolonging battery life.  
Key MIC2937A features include protection against reversed  
battery,fold-backcurrentlimiting,andautomotiveloaddump”  
protection (60V positive transient).  
Guaranteed 750mA output  
Low quiescent current  
Low dropout voltage  
Extremely tight load and line regulation  
Very low temperature coefficient  
Current and thermal limiting  
Input can withstand –20V reverse battery and +60V posi-  
tive transients  
The MIC2937 is available in several configurations. The  
MIC2937A-xx devices are three pin fixed voltage regulators  
with 3.3V, 5V, and 12V outputs available. The MIC29371 is  
a fixed regulator offering logic compatible ON/OFF switching  
input and an error flag output. This flag may also be used as  
a power-on reset signal. A logic-compatible shutdown input  
is provided on the adjustable MIC29372, which enables the  
regulator to be switched on and off.  
Error flag warns of output dropout  
Logic-controlled electronic shutdown  
Output programmable from 1.24V to 26V(MIC29372)  
Available in TO-220, TO-263, TO-220-5, and TO-263-5  
packages.  
Applications  
Battery Powered Equipment  
Cellular Telephones  
Laptop, Notebook, and Palmtop Computers
