Abstract
A switching regulator includes a first differential amplifier outputting an amplified difference voltage obtained by amplifying a difference between a reference voltage and a feedback voltage in proportion to an output voltage; a second differential amplifier including a differential pair of a first transistor and a second transistor, the second differential amplifier outputting an error voltage based upon the amplified difference voltage supplied to each gate of the first transistor and the second transistor; a pulse wide modulation circuit converting the error voltage into a PWM signal; a first resistor containing a first end connected to the source of the first transistor; a second resistor containing a first end connected to the source of the second transistor; and a capacitor containing a first end connected to the source of the first transistor and the first end of the first resistor.
