The MIC4043 is a shunt regulator optimized for secondaryside regulation in low-voltage power supplies.
Featuring an output stage guaranteed to swing within 400mV of ground, the MIC4043 can be used in power supplies operating down to 1.8V, even with opto-isolators requiring greater than 1.2V of headroom.
In power supply applications, the MIC4043 normally drives the LED of an optically isolated feedback circuit.
