Micrel MIC5392-2.8 High-performance dual 150ma ldo Datasheet

MIC5392/3
High-Performance Dual 150mA LDO
Revision 1.2
General Description
Features
The MIC5392/3 is a tiny dual low-dropout linear regulator
ideally suited for portable electronics. It is ideal for general
purpose/digital applications which require high-power
supply ripple rejection (PSRR) >60dB, eliminating the need
for a bypass capacitor and providing two enable pins for
maximum flexibility. The MIC5392/3 integrates two highperformance; 150mA LDOs into a tiny 6-pin, 1.2mm x
1.2mm leadless DFN package, which provides exceptional
thermal package characteristics.
The MIC5392/3 is a µCap design which enables operation
with very small ceramic output capacitors for stability,
thereby reducing required board space and component
cost. The combination of low-drop-out voltage, high power
supply rejection and exceptional thermal package
characteristics makes it ideal for powering mobile phones
camera modules, image sensors, PDAs, MP3 players and
audio codec power applications.
The MIC5392/3 is available in fixed-output voltages in the
tiny 6-pin 1.2mm x 1.2mm leadless DFN package which is
2
only 1.44mm in area. Additional voltage options are
available.
