レータ。Switching element and this switchable element are turned ON and OFF.
In a switching regulator including an error amplifier that performs FF control and a smoothing circuit that smoothes the switching output of the switching element, an operational amplifier is used as the error amplifier, a reference voltage is applied to one input terminal of the operational amplifier, and a reference voltage is applied to one input terminal of the operational amplifier. A switching regulator characterized in that a voltage on the output side of the smoothing circuit is applied to the other input terminal, and a hysteresis characteristic of switching operation is obtained by input/output response delay of the operational amplifier.
