MIC5330
Dual 300mA µCap LDO in 2mm x 2mm MLF^®
General Description
The MIC5330 is a tiny Dual Ultra Low Dropout
(ULDO™) linear regulator ideally suited for portable
electronics due to its high power supply ripple
rejection (PSRR) and ultra low output noise. The
MIC5330 integrates two high performance 300mA
ULDOs into a tiny 2mm x 2mm leadless MLF^®
package, which provides exceptional thermal package
characteristics.
The MIC5330 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 extremely
low drop out voltage, high power supply rejection and
exceptional thermal package characteristics makes it
ideal for powering RF/noise sensitive circuitry, cellular
phone camera modules, imaging sensors for digital
still cameras, PDAs, MP3 players and WebCam
applications.
The MIC5330 ULDO™ is available in fixed output
voltages in the tiny 8-pin 2mm x 2mm leadless MLF^®
package which occupies less than half the board area
of a single SOT-6 package. Additional voltage options
are available. For more information, contact Micrel
marketing department.
