The MIC5311 is a high performance, dual µCap low dropout regulator offering ultra-low operating current and a second, even lower operating current mode, LowQ^® mode, reducing operating current by 75%. Each regulator can source up to 300mA of output current maximum.

Ideal for battery operated applications, the MIC5311 offers 1% accuracy, extremely low dropout voltage (60mV @ 150mA), and low ground current (typically 28 µA total). When put into LowQ^® mode, the internal current draw drops down to 7µA total. The MIC5311 also comes equipped with a TTL logic compatible enable pin that allows the part to be put into a zero off-mode current state, drawing no current when disabled.

The MIC5311 is a µCap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost.
