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.
