Abstract
A method and an apparatus of an internal voltage down converter having good transient response characteristics and small chip real estate, includes a differential amplifier for comparing a voltage on an internal power supply line with a reference voltage, a MOS transistor for generating an internal supply voltage from an external supply voltage, by receiving the output of the differential amplifier at the gate, and a feed back capacitive element provided between the internal power supply line and the gate of the MOS transistor.
