MIC5310-1.5YML

Manufacturer Part Number
MIC5310-1.5YML
Description
Dual, 150mA uCap LDO in 2mm x 2mm MLF
Manufacturer
MICREL [Micrel Semiconductor]
Datasheet
General Description
The MIC5310 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
MIC5310 integrates two high-performance; 150mA
ULDOs into a tiny 2mm x 2mm leadless MLF
package, which provides exceptional thermal package
characteristics.
The MIC5310 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 MIC5310 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.
