Device Overview

Summary

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.
