General Description
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
into a tiny 2mm x 2mm leadless Thin MLF
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
which occupies less than half the board area of a single
SOT23-6
available. For more information, contact Micrel marketing.

... RF-based circuit. Output Capacitor The MIC5350 requires an output capacitor of 2.2µF or greater to maintain stability. The design is optimized for use with low-ESR ceramic chip capacitors. High-ESR capacitors may cause high-frequency oscillation. The output capacitor can be increased, but performance has been optimized for a 2.2µ ...
