MIC5304-XGHYMT-TR Microchip

MIC5304 Single 150mA Low Operating Current LDO with Dual Voltage Pin Select General Description Features The MIC5304 is a low quiescent current, low dropout 150mA output current regulator with selectable output voltage designed for Logic controlled selectable output voltage applications that require two levels of output voltage Fast transition time between selected output voltages regulation. The MIC5304 is an ideal solution for Input voltage range: 2.3V to 5.5V programming memory cards as well as for conserving power in portable applications. The MIC5304 is capable of Low 24A operating current sourcing 150mA of output current while only consuming Stable with 1F ceramic capacitors 24A of operating current. This high performance LDO Low dropout voltage of 85mV 150mA offers fast transient response while still maintaining low Thermal shutdown and current limit protection quiescent current levels. Tiny 6-pin 1.6mm x 1.6mm Thin MLF package The MIC5304 is an ideal solution for battery operated applications due to ultra low operating current and extremely low dropout voltage of 85mV at 150mA. Applications Equipped with a TTL logic compatible enable pin, the Mobile phones, PDAs, PMPs, PNDs MIC5304 can be put into a zero-off mode current state, drawing virtually no current when disabled. Digital still and video cameras Board space and component cost is minimized because Dual voltage levels for power saving mode the MIC5304 operates with very small 1F ceramic Portable electronics capacitors. The MIC5304 provides fixed output voltages, and is available in the tiny 1.6mm x 1.6mm Thin MLF package ideal for portable electronics. MIC5304 also features thermal shutdown and current limit protection. Data sheets and support documentation can be found on Micrels web site at: www.micrel.com.
