Power control is facilitated. In accordance with one or more embodiments, power is supplied to power rails of an integrated circuit using a power control circuit including a power regulator and a reset circuit that is responsive to a supply voltage. The power regulator provides power to the power rails, based upon a control signal. The reset circuit controls the power regulator to provide power to the power rails independently of the control signal when the supply voltage is below an operational voltage level, and controls the power regulator to provide power to the power rails in response to the control signal when the supply voltage reaches the operational voltage level.
