MIC5355/6
Dual 500mA µCap Low Dropout,
Micropower Linear Regulator
General Description
The MIC5355/6 is an advanced dual, micropower, low
dropout linear regulator. The MIC5355/6 provides low
quiescent current operation, using only 70μA with both
outputs enabled making it ideal for battery-powered
systems. In shutdown, the quiescent current drops to less
than 1µA. The MIC5355/6 provides two independently-
controlled high-performance 500mA LDOs with typical
dropout voltage of 350mV at rated load. In addition, the
MIC5355/6 is optimized to provide fast load and line
transient performance with low-ESR ceramic output
capacitors, requiring a minimum of only 2.2µF.
The MIC5356 also incorporates an active discharge
feature when the part is disabled that switches in a 30
load to pull down the output of the regulator. The
MIC5355/6 is available in fixed output voltages in a
thermally-enhanced 8-pin ePad MSOP package or 8-pin
ePad 3mm x 3mm MLF® package.
