Abstract:
1. A booster circuit comprising: an output terminal; a reference voltage generating section that generates a boosting reference voltage; a charge pump section that boosts the reference voltage and outputs the boosted reference voltage via the output terminal; and an output-terminal voltage holding section that holds the output terminal at a voltage of a high level at a standby time, wherein, (1) the charge pump section includes (2) at the standby time, the output-terminal voltage holding section connects an output side of the reference voltage generating section or the output terminal to a potential equivalent to the high level, and controls an on/off action of those of the switching transistors which are connected between at least the input node in the charge pump section and the output terminal, depending on whether the potential equivalent to the high level is connected to the output side of the reference voltage generating section or the output terminal.
