General Description
The MIC5357 is a tiny Dual Ultra Low Dropout (ULDO)
linear regulator ideally suited for portable electronics due
to its low output noise. The MIC5357 provides two
independently controlled high performance 500mA LDOs
with typical dropout voltage of 130mV at rated load. In
addition, the MIC5357 provides a bypass pin to reduce the
output noise.
The MIC5357 is designed to be stable with small ceramic
output capacitors thereby reducing required board space
and component cost. The combination of extremely low
dropout 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 MIC5357 ULDO is available in fixed output voltages
in the small 8-pin ePad MSOP package. Additional voltage
options are available. For more information, contact Micrel
marketing.
