Abstract
A system supply voltage, supplied from an external supply circuit, is lowered to generate an internal supply voltage for an internal circuit when the system supply voltage is higher than a breakdown voltage of the internal circuit. The system supply voltage is directly supplied to the internal circuit when the system supply voltage is not higher than the breakdown voltage of the internal circuit.
