ABSTRACT:
Provided is a switching regulator having an improved power supply voltage variation response characteristic while maintaining the stability of an output voltage to oscillation. An output resistance of an error amplifier is adjusted by a power supply voltage variation response improving circuit to allow a gain of the error amplifier to change.
