The MIC5312 is a high performance, dual µCap low dropout regulator with integrated power-on reset supervisor, 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 MIC5312 offers 1% accuracy, extremely low dropout voltage (60mV @ 150mA), and low ground current (typically 28µA total). When put into LowQ® mode, the internal current draw drops down to 7µA total. The MIC5312 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 Power-on Reset is active low and indicates an output undervoltage condition on either regulator 1 or 2 when the regulator is enabled.
The MIC5312 is a µCap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost.
