電源制御回路。a first circuit for supplying operating current using a voltage regulating resistor that reduces the voltage supplied from the power supply to a predetermined voltage and supplies operating current to the load section; and a circuit that is parallel to the resistor of the first circuit. When the load section is provided with a high load or an overload, the voltage drop across the resistor becomes significant and a sufficient operating current cannot be supplied to the load section. A power supply control circuit comprising: a second circuit for supplying operating current using a switching element and a current supplying element for supplying operating current to the load section in place of the circuit.
