MIC5303
Single 300mA CMOS
Ultra Small ULDO?
General Description
Features
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

Ultra Small 1.2mm x 1.6mm Thin MLF ? package
Low Dropout Voltage: 100mV at 300mA
Output noise 120μVrms
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
High output accuracy
– ±2% initial accuracy
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 2 of
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.
– ±3% over temperature
? Thermal shutdown and current limit protection
Applications
? Mobile Phones
? PDAs
? GPS Receivers
