タ。 Switching that has a capacitor for output ripple detection in parallel with a resistor that divides the output voltage, inputs the divided voltage to the error amplifier in the pulse width control IC to control the pulse width, and controls the output voltage at a constant voltage. In the regulator, a series circuit of a resistor and a capacitor is connected in parallel with the divided voltage detection resistor, and a diode is connected in parallel with this resistor in a direction to discharge the charge of the capacitor. Features a switching regulator.
