This circuit is about the MAX663's on-off control circuit. If the Vset terminal is grounded, the output voltage of the external resistor can be set to 5V. In this case, you can choose whether overcurrent protection is required. If the SHDN pin is used, the regulator can be turned on/off by an external signal. When the SHDN terminal is low, the regulator operates. When the regulator is high, the regulator is turned off. The load current is not supplied at the time of the cutoff, and the regulator consumes the minimum current, so the system can save power.
