ABSTRACT:
An on-chip voltage regulator for controlling a gate of a regulator transistor having a first terminal coupled to receive an external power supply voltage and a second terminal coupled to provide a regulated voltage level to an internal circuit formed on a chip on which the on-chip voltage regulator is formed. The on-chip voltage regulator includes circuitry for detecting when a high current load to which the second terminal of the regulator transistor is coupled is activated. A control transistor is provided having a first terminal coupled to receive the external power supply voltage, a second terminal coupled to the gate of the regulator transistor, and a gate responsive to the means for detecting. In operation, a control voltage with an overshoot portion having preselected duration is generated on the gate of the regulator transistor in response to the activation of the high current load.
