MIC5350
Dual 300mA/500mA LDO
in 2mm x 2mm Thin MLF^®
General Description
Features
The MIC5350 is a tiny Dual Ultra Low-Dropout (ULDO™)
linear regulator ideally suited for portable electronics due
to its low output noise. The MIC5350 integrates two high-
performance; 300mA (V_OUT1) and 500mA (V_OUT2) ULDOs™
into a tiny 2mm x 2mm leadless Thin MLF^® package,
which provides exceptional thermal characteristics.
The MIC5350 is designed to be stable with small ceramic
output capacitors thereby reducing required board space
and component cost. The combination of extremely low-
drop-out voltage, low output noise and exceptional thermal
package characteristics makes it ideal for powering RF
and noise-sensitive circuitry, cellular phone camera
modules, imaging sensors for digital still cameras, PDAs,
MP3 players and WebCam applications.
The MIC5350 ULDO™ is available in fixed-output voltages
in the tiny 8-pin 2mm x 2mm leadless Thin MLF^® package
which occupies less than half the board area of a single
SOT23-6 package. Additional voltage options are
available. For more information, contact Micrel marketing.
