MIC5303

Single 300mA CMOS

Ultra Small ULDO™

General Description

The MIC5303 is an ultra small, Ultra Low Dropout CMOS

regulator, ULDO™ that is ideal for today’s most demand-

ing portable applications including cellular phone RF

power, camera modules, imaging sensors for digital still

and video cameras, PDAs, portable media players (PMP)

and PC cameras where board space is limited. It offers

extremely low dropout voltage, very low output noise and

can operate from a 2.3V to 5.5V input while delivering up

to 300mA.

It offers 2% initial accuracy, low ground current (typically

85µA total), thermal and current limit protection. The

MIC5303 can also be put into a zero-off-mode current

state, drawing no current when disabled.

The MIC5303 is available in the ultra small 4-pin 1.2mm x

1.6mm Thin MLF

package, occupying only 1.92mm

PCB area, a 50% reduction in board area compared to

SC-70 and 2mm x 2mm MLF

packages. It’s operating

junction temperature range is –40°C to +125°C and is

available in fixed output voltages in lead-free (RoHS

compliant) Thin MLF

package.
