Title:
Multi-mode voltage supply circuit
Abstract:
A supply voltage is provided in an integrated circuit by retrieving an indicator from a storage device and generating a supply voltage for use by the integrated circuit, the supply voltage being regulated responsive to the indicator being in a first state and unregulated responsive to the indicator being in a second state. Alternatively or additionally, an external voltage provided to the integrated circuit is compared with a threshold. The supply voltage is regulated responsive to the external voltage exceeding the threshold level and unregulated responsive to the external voltage falling below the threshold level.
