com 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.
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.
