Provides a switching regulator control circuit, a switching regulator and a switching regulator control method for achieving low current consumption and quick response at normal operating time. A change-over switch MFB for opening/closing the phase compensation is provided to establish both the quick responsibility using a gain of an error amplifier EA provided with no phase compensation and stability of control system provided with phase compensation. By turning the change-over switch MFB non-conductive at a timing in which the PMOS transistor M1 turns to conductive, the phase compensation between the input and output of the error amplifier EA is cut off. A detection voltage VM is amplified in term of error with a gain of the error amplifier EA itself. A quick transient response to changes in the output voltage VOUT is achieved corresponding to maximum response characteristic. Phase compensation between the input and output of the error amplifier EA is formed by turning the change-over switch MFB conductive at a timing in which the PMOS transistor M1 turns to non-conductive. Consequently, stability of the control system can be secured.
