ABSTRACT:
An on-chip voltage regulator controls a gate of a regulator transistor having a first terminal connectable to receive an external power supply voltage and a second terminal connectable to an internal circuit formed on a chip on which the on-chip voltage regulator is formed. The regulator includes a clock receiving part for receiving a predetermined clock signal related to an operation of the internal circuit, and a regulator part for generating a gate voltage output to the gate of the regulator transistor on the basis of a state of the predetermined clock signal so that the regulator transistor can generate a substantially fixed internal voltage from the external power supply voltage irrespective of whether or not the internal circuit is operating.
