MIC2940A/2941A  
1.25A Low-Dropout Voltage Regulator  
Preliminary Information  
General Description  
Features  
High output voltage accuracy  
Guaranteed 1.25A output  
The MIC2940A and MIC2941A are “bulletproof” efficient  
voltage regulators with very low dropout voltage (typically  
40mV at light loads and 350mV at 1A), and low quiescent  
current(240µAtypical).ThequiescentcurrentoftheMIC2940A  
increases only slightly in dropout, thus prolonging battery life.  
Key MIC2940A features include protection against reversed  
battery,fold-backcurrentlimiting,andautomotiveloaddump”  
protection (60V positive transient).  
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  
positive transients  
The MIC2940 is available in both fixed voltage (3.3V, 5V, and  
12V) and adjustable voltage configurations. The MIC2940A-  
xx devices are three pin fixed voltage regulators. A logic-  
compatible shutdown input is provided on the adjustable  
MIC2941A,whichenablestheregulatortobeswitchedonand  
off.  
Logic-controlled electronic shutdown  
Output programmable from 1.24V to 26V(MIC2941A)  
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  
PCMCIA VCC and VPP Regulation/Switching  
Bar Code Scanners
