MIC5325
Low VIN/VOUT 400mA ULDOâ¢
with Ultra-Low IQ
General Description
The MIC5325 is a high-performance, µCap, low-dropout
regulator, offering ultra-low operating current while
maintaining very fast transient response. The MIC5325
can source up to 400mA of output current and allows a low
input supply voltage source to increase system efficiency.
Ideal for battery operated applications; the MIC5325 offers
high accuracy, extremely low dropout voltage, and low
ground current at all load conditions. The MIC5325 can
also be put into a zero-off-mode current state, drawing
virtually no current when disabled.
The MIC5325 is available in fixed-output voltages in the
6-pin 2mm x 2mm Thin MLF® leadless package.
Data sheets and support documentation can be found on
Micrelâs web site at www.micrel.com.
