Abstract
Disclosed is a band gap power supply circuit including a band gap core circuit to perform control in such a way that the sum of a current flowing through a diode and a current flowing through a first current path becomes equal to the sum of a current flowing through a diode and a current flowing through a second current path, and the sum of the forward direction voltage of the diode and a voltage drop across a resistor becomes equal to the forward direction voltage of the diode; and a switch control circuit to control a switch and a switch from off to on at a time of a startup of a power supply.
