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.Ultra-small 1.2mm x 1.6mm Thin MLF® package Low dropout voltage: 50mV at 150mA Output noise 120µVrms Input voltage range: 2.3V to 5.5V 150mA guaranteed output current Stable with ceramic output capacitors Low quiescent current 85µA total 35µs turn-on time High output accuracy ±2% initial accuracy ±3% over temperature Thermal-shutdown and current-limit protection
