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
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.
Data sheets and support documentation can be found on
Micrel’s web site at www.micrel.com.

. Exceeding the maximum allowable power
dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
4. Specification for packaged product only.
5. Regulation is measured at constant junction temperature using low duty cycle pulse testing, changes in output voltage due to heating effects are
covered by the thermal regulation specification.
6. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value measured at 1V differential.
7. Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of the load current plus the ground pin
current.
