Abstract
A semiconductor apparatus includes an internal circuit connected to a first power line to which a first power voltage is applied; a transistor including a first terminal, which is connected to a node to which an input voltage is applied, a second terminal connected to the internal circuit, and a control terminal to which a control voltage is applied; and a voltage control circuit, which is connected to the node, generating the control voltage. Further, the voltage control circuit includes a step-down circuit generating an internal voltage by lowering the input voltage applied to the node, and a switching circuit, which is connected to the first power line, generating the control voltage based on the first power voltage and the internal voltage.
