... AC filter capacitor battery is used as the input. Error Detection Comparator Output (MIC29371) A logic low output will be produced by the comparator when- ever the MIC29371 output falls out of regulation by more than approximately 5%. This figure is the comparator’s built-in offset of about 75mV divided by the 1.235V reference volt- age. (Refer to the block diagram on Page 1). This trip level remains “ ...
