Supply control circuit and dry -battery powered equipment

The utility model provides a supply control circuit and dry -battery powered equipment, wherein, the supply control circuit includes low -power consumption treater, first power supply branch road andsecond power supply branch road, first power supply branch road directly transmits the power supply voltage of dry battery to the output module of dry -battery powered equipment when making the ability state. Second power supply branch road carries out the steady voltage adjustment to the power supply voltage of dry battery when making the ability state, utilize the adjusted voltage of steady voltage to provide power supply voltage for output module. The low -power consumption treater can first power supply branch road if make when judging futilely battery voltage and being located output module operating voltage range, makes the ability second branch road of supplying power not in output module's operating voltage range the time if judge futilely battery voltage. Therefore, the utility model discloses do battery
