MIC5326-2.8YMT-TR Microchip

MIC5326 150mA Low Operating Current LDO General Description Features The MIC5326 is a low quiescent current, low dropout 150mA output current regulator designed for optimal performance in a small Input voltage range: 2.3V to 5.5V space. The MIC5326 is capable of sourcing 150mA of Low 24A operating current output current while only consuming 24A of operating Low dropout voltage of 85mV 150mA current. This high performance LDO offers low dropout, fast transient response, good PSRR, and low output Fixed output voltage voltage noise. Stable with 1F ceramic capacitors The MIC5326 is an ideal solution for battery operated Thermal shutdown and current limit protection applications due to low operating current of 24 A and Tiny 4-pin 1.2mm x 1.6mm Thin MLF package extremely low dropout voltage of 85mV at 150mA. Equipped with a TTL logic compatible enable pin, the MIC5326 can be put into a zero-off-mode current state Applications drawing virtually no current when disabled. Mobile handsets Board space and component cost is minimized because GPS and navigation devices the MIC5326 operates with very small 1F ceramic Portable media players capacitors, provides fixed output voltages, and is available in the tiny 1.2mm x 1.6mm Thin MLF package. Digital still and video cameras MIC5326 also features thermal shutdown and current limit PDAs protection.
