Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce the power consumption both in an operation mode state and in a stand-by mode state. SOLUTION: A charge pump circuit, connected between a reference voltage line and an output terminal, has at least two circuit stages having respective charge pump circuit elements. The circuit stages are connected between the reference voltage line and the output terminal, respectively. Further, the charge pump circuit has a control circuit, connected between the output terminal and the control terminals of the respective two circuit stages. The charge pump circuit selects a proper combination of the circuit stages, according to the current absorbed by a load connected to the output terminal.
