MIC5303

Single 300mA CMOS

Ultra Small ULDO™

General Description

Features

• Ultra Small 1.2mm x 1.6mm Thin MLF^®package

• Low Dropout Voltage: 100mV at 300mA

• Output noise 120µVrms

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.

• Input voltage range: 2.3V to 5.5V

• 300mA guaranteed output current

• Stable with ceramic output capacitors

• Low quiescent current 85µA total

• 35µs turn-on time

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.

• High output accuracy

– ±2% initial accuracy

– ±3% over temperature

• Thermal shutdown and current limit protection

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

1.6mm Thin MLF^®package, occupying only 1.92mm²of

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.

Applications
