Abstract: Voltage supply and method having a first reference and a second reference. The first reference has an operation mode configured to supply a first reference voltage at a first accuracy and consume an operation power and a standby mode configured to consume standby power less than the operation power. The second reference is configured to supply a second reference having a second accuracy less than the first accuracy of the first reference and which consumes a second reference power less than the operation power of the first reference, the second reference voltage being trimmable based, at least in part, on a comparison of the first reference voltage to the second reference voltage.
