Abstract
The step-down regulator includes a first error amplifying circuit that receives a first reference voltage and the first voltage and supplies a first control signal to a control terminal of the first transistor so that the first reference voltage and the first voltage are equal to each other. The step-down regulator includes a second error amplifying circuit that receives a voltage at the second end of the current controlling circuit and a second reference voltage and supplies a second control signal to the current controlling circuit so that the voltage at the second end of the current controlling circuit and the second reference voltage are equal to each other. The step-down regulator includes a diode that is connected to the second end of the current controlling circuit at an anode thereof and to the second potential at a cathode thereof.
