MIC2954  
250mA Low-Dropout Regulator  
General Description  
Features  
The MIC2954 is a “bulletproof” efficient voltage regulator  
with very low dropout voltage (typically 40mV @ light loads  
and 375mV @ 250mA), and low quiescent current (120µA  
typical). The quiescent current of the MIC2954 increases  
only slightly in dropout, thus prolonging battery life. Key  
MIC2954 features include protection against reversed  
battery, fold-back current limiting, and automotive load  
dump protection (60V positive transient).  
High-accuracy 5V, guaranteed 250mA 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  
positive transients  
The MIC2954-07/08BM is an adjustable version that  
includes 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 provided which enables the  
regulator to be switched on and off. This part may be pin-  
strapped for 5V output, or programmed from 1.24V to 29V  
with the use of two external resistors.  
Error flag warns of low output voltage  
Logic-controlled electronic shutdown  
Output programmable from 1.24V to 29V  
(MIC2954-07/08)  
Available in TO-220, TO-92, and surface-mount SOT-  
223 and SOIC-8 packages  
Applications  
The MIC2954 is available in two voltage tolerances, ±0.5%  
maximum and ±1% maximum. Both are guaranteed for  
junction temperatures from –40°C to +125°C.  
Battery powered equipment  
Cellular telephones  
Laptop, notebook, and palmtop computers  
PCMCIA VCC and VPP regulation/switching  
Bar code scanners
