The MIC5309-1.2YMT TR is a 1.2V fixed output high performance µCap low-dropout (LDO) Linear Regulator offers ultra-low operating current while maintaining very fast transient response. The device can source up to 300mA of output current and can regulate down from a low input supply voltage to increase system efficiency. The device offers extremely low-dropout (LDO) voltage (100mV typically at 300mA load) and low ground current at all load conditions (typically 23µA). The device can also be put into a zero OFF-mode current state, drawing virtually no current when disabled.
