An electronic system includes first, second, third, and fourth integrated circuit dies. The third integrated circuit die has a first voltage regulator circuit. A supply voltage output of the first voltage regulator circuit is coupled to provide a first supply voltage to a supply voltage input of the first integrated circuit die. The first voltage regulator circuit generates a first power ready signal that indicates when the first supply voltage has reached a first threshold voltage. The fourth integrated circuit die has a second voltage regulator circuit that generates a second supply voltage in response to the first power ready signal. A supply voltage output of the second voltage regulator circuit is coupled to provide the second supply voltage to a supply voltage input of the second integrated circuit die.
