MIC5302-3.3YMT TR Microchip

MIC5302 150mA ULDO in Ultra-Small 1.2mm x 1.6mm Thin MLF General Description Features The MIC5302 is an ultra-small, ultra-low dropout CMOS Ultra-small 1.2mm x 1.6mm Thin MLF package regulator, ULDO that is ideal for todays most Low dropout voltage: 50mV at 150mA demanding portable applications including cellular phone Output noise 120Vrms RF power, camera modules, imaging sensors for digital Input voltage range: 2.3V to 5.5V still and video cameras, PDAs, portable media players (PMP) and PC cameras where board space is limited. It 150mA guaranteed output current offers extremely-low dropout voltage, very-low output Stable with ceramic output capacitors noise and can operate from a 2.3V to 5.5V input while Low quiescent current 85A total delivering up to 150mA. 35s turn-on time It offers 2% initial accuracy, low ground current (typically High output accuracy 85A total), thermal- and current-limit protection. The 2% initial accuracy MIC5302 can also be put into a zero-off-mode current state, drawing no current when disabled. 3% over temperature The MIC5302 is available in the ultra small 4-pin 1.2mm x Thermal-shutdown and current-limit protection 2 1.6mm Thin MLF package, occupying only 1.92mm of Applications PCB area, a 50% reduction in board area compared to SC-70 and 2mm x 2mm MLF packages. Its operating Mobile Phones junction temperature range is 40C to +125C and is PDAs available in fixed output voltages in lead-free (RoHS GPS Receivers compliant) Thin MLF package.
