Integrated circuit device, voltage regulation circuitry and method for regulating a voltage supply signal

An integrated circuit (IC) device comprising:

• at least one internal voltage regulator arranged to
• receive a voltage supply signal at a first input thereof,
• receive a control signal at a second input thereof,
• regulate the received voltage supply signal in accordance with the received control signal, and
• provide a regulated voltage supply signal at an output thereof;
• at least one voltage regulation power control module operably coupled to the second input of the at least one internal voltage regulator and arranged to
• provide the control signal thereto,
• receive at least one IC device conditional indication, and
• generate the control signal for the least one internal voltage regulator based at least partly on an available thermal power budget for the IC device corresponding to the at least one IC device conditional indication, wherein the at least one voltage regulation power control module is arranged to generate the control signal to cause the at least one internal voltage regulator to enter a bypass mode, and, in response to the control signal, the at least one internal voltage regulator provides the received voltage supply signal unregulated at an output thereof, if the available thermal power budget for the IC device corresponding to the at least one IC device conditional indication is less than a threshold value.
