Microchip | MIC5304-XDYMT-TR

The MIC5304-XDYMT TR is a low quiescent current, low dropout regulator with selectable output voltage designed for applications that require two levels of output voltage regulation. The MIC5304 is an ideal solution for programming memory cards as well as for conserving power in portable applications. The MIC5304 is capable of sourcing 150 mA of output current while only consuming 24 µA of operating current. This high performance LDO offers fast transient response while still maintaining low quiescent current levels.

The MIC5304 is an ideal solution for battery operated applications due to ultra low operating current and extremely low dropout voltage of 85 mV at 150 mA. Equipped with a TTL logic compatible enable pin, the MIC5304 can be put into a zero-off mode current state, drawing virtually no current when disabled. Board space and component cost is minimized because the MIC5304 operates with very small 1 µF ceramic capacitors. The MIC5304 provides fixed output voltages, and is available in the tiny 1.6 mm x 1.6 mm Thin MLF® package ideal for portable electronics. MIC5304 also features thermal shutdown and current limit protection.
