Low-power, high-performance voltage regulator circuit devices are disclosed and described. In one embodiment, such a device can include a first stage circuitry configured to generate a high voltage reference from a low voltage reference, a second stage circuitry coupled to the first stage circuitry, the second stage circuitry configured to receive the high voltage reference and output a voltage regulated signal, and a switch disposed between and coupled to the first stage circuitry and the second stage circuitry, the switch being configured to couple and uncouple the first stage circuitry from the second stage circuitry.
