MIC5302
150mA ULDO™ in Ultra-Small
1.2mm x 1.6mm Thin MLF^®
General Description
The MIC5302 is an ultra-small, ultra-low dropout CMOS
regulator, ULDO™ that is ideal for today’s most
demanding 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 150mA.
It offers 2% initial accuracy, low ground current (typically
85µA total), thermal- and current-limit protection. The
MIC5302 can also be put into a zero-off-mode current
state, drawing no current when disabled.
The MIC5302 is available in the ultra small 4-pin 1.2mm x
1.6mm Thin MLF^® package, occupying only 1.92mm² of
PCB area, a 50% reduction in board area compared to
SC-70 and 2mm x 2mm MLF^® packages. Its 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.
