1. A microelectronic power regulator for regulating power to a microprocessor, comprising:
- a first power regulator; and
a sense circuit configured to sense a rate of change of power distributed to the microprocessor, wherein the sense circuit is configured to send a signal to the first power regulator, the signal indicative of the rate of change of power distributed to the microprocessor.

Abstract
A device for providing power to suppress transient load demands and a system including the device are disclosed. The device includes a sense circuit to detect when a transient event occurs and one or more transistors configured to supply or sink current to the load. The system may include a second power regulator configured to respond to fast transient power demands. In this case, a first power regulator supplies power to the load and responds to slow transient events, while the second regulator responds only to fast transient events.
