AbstractA reference-producing integrated circuit that is able to rapidly transition from an enable mode to a disable mode is disclosed. The reference-producing integrated circuit can, for example, be a voltage reference integrated circuit or a voltage regulator. In one implementation, the voltage reference integrated circuit or the voltage regulator can provide a low dropout voltage output. The reference-producing integrated circuit is particularly useful for reducing power consumption by electrical circuitry (e.g., portable computing devices) being power managed at least in part through control of the voltage reference supplied to the electrical circuitry.
