General Description

The MIC5304 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 150mA of output current while only consuming 24µA of operating current. This high performance LDO offers fast transient response while still maintaining low quiescent current levels.
