Abstract
A low power voltage reference circuit is provided, it has a normal operating mode and a low power mode. In the low power mode, a startup circuit is isolated and operates in low power, and the voltage reference portion of the circuit also operates in low power and provides low voltage output. When the circuit is instead enabled, the startup circuitry forced the referenced circuitry out of its low power mode and into a stable, reference mode.
