Abstract:
1. A voltage generating circuit comprising: a first step-down transistor including a gate controlled by a first voltage and a drain connected to a first high potential side power source side, and outputting, from a source of the first step-down transistor, a second high potential side supply voltage obtained by stepping down the first high potential side supply voltage, in an active state which allows a flow of a first consumption current; a second step-down transistor including a gate controlled by the first voltage and a drain connected to the first high potential side power source, and outputting the second high potential side supply voltage from a source of the second step-down transistor in the active state and in a standby state which allows a flow of a second consumption current whose amount is less than that of the first consumption current; and a gate voltage stabilizing circuit including when the standby state changes to the active state, when the active state changes to the standby state,
