Microchip Technology

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. 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. 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 1µF ceramic capacitors. The MIC5304 also features thermal shutdown and current limit protection.

The MIC5305 is a high-performance, 150mA LDO regulator, offering extremely high PSRR and very low noise while consuming low ground current. Ideal for battery-operated applications, the MIC5305 features 1% accuracy, extremely low dropout voltage (60mV at 150mA), and low ground current at light load (typically 90µA). Equipped with a logic-compatible enable pin, the MIC5305 can be put into a zero-off-mode current state, drawing no current when disabled. The MIC5305 is a µCap design operating with very small ceramic output capacitors for stability, thereby reducing required board space and component cost.

The MIC5307 is a micropower, µCap low dropout regulator designed for optimal performance where smaller packages are required. It is capable of sourcing 300mA of output current while only drawing 20µA of operating current. This high performance LDO offers fast transient response and good PSRR while consuming a minimum of current. Ideal for battery-operated applications, the MIC5307 offers 1% initial accuracy, extremely low dropout voltage and is equipped with a TTL logic-compatible enable pin. The MIC5307 can be put into a zero off-mode current state, drawing no current when disabled. The MIC5307 is a µCap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost. The MIC5307 is available in fixed output voltages in the Thin SOT23-5 package.

The MIC5308 is a high performance, µCap low dropout regulator, offering ultra-low operating current while maintaining very fast transient response. The MIC5308 can source up to 150mA of output current and can regulate down from a low input supply voltage to increase system efficiency. Ideal for battery-operated applications; the MIC5308 offers extremely low dropout voltage (45mV typically at 150mA) and low ground current at all load conditions (typically 23µA). The MIC5308 can also be put into a zero off-mode current state, drawing virtually no current when disabled.

The MIC5309 is a high performance, µCap low dropout regulator that offers ultra-low operating current while maintaining very fast transient response. The MIC5309 can source up to 300mA of output current and can regulate down from a low input supply voltage to increase system efficiency. Ideal for battery-operated applications; the MIC5309 offers extremely low dropout voltage (100mV typically at 300mA load) and low ground current at all load conditions (typically 23µA). The MIC5309 can also be put into a zero off-mode current state, drawing virtually no current when disabled.
