Abstract:
1. A switching regulator comprising: an error amplifier that amplifies a difference between a divided voltage and a reference voltage, the divided voltage being obtained by dividing an output voltage, the divided voltage connected to an inverting input of the error amplifier, the error amplifier outputting an output signal comprising the amplified difference, wherein a magnitude of the output signal directly corresponds with changes in an output load current of the switching regulator; an oscillation circuit that outputs a rectangular wave in accordance with an output signal from the error amplifier, the oscillation circuit including a switching element, an ON/OFF state of the switching element being controlled by an output signal from the oscillation circuit, wherein an oscillation frequency of the oscillation circuit increases and decreases in direct correspondence with the output signal from the error amplifier and the output load current.
