Abstract: A semiconductor circuit includes a reference voltage generating circuit which generates a first reference voltage; a voltage control circuit which receives the first reference voltage from the reference voltage generating circuit to output a second reference voltage; a DC-DC conversion circuit which executes DC-DC conversion on the basis of the second reference voltage which is output from the voltage control circuit, and provides an output thereof to a first node; and a voltage regulator which executes voltage regulating on the basis of the first reference voltage which is output from the reference voltage generating circuit, and a voltage of the first node, and provides an output thereof to a second node.
