ABSTRACT:
A voltage regulator for supplying power to volatile memory cells during a suspend mode of an integrated circuit is described. The integrated circuit in an awake mode generates a regulated voltage at an output node using a first supply voltage and in the suspend mode generates the regulated voltage at the output node using a second supply voltage, at less voltage than the first supply voltage. The second supply voltage is electrically decoupled from the output node for transitioning from the suspend mode to the awake mode, and the first supply voltage is electrically decoupled from the output node for transitioning from the awake mode to the suspend mode.
