| Zusammenfassung: | The invention discloses a voltage regulator. The voltage regulator circuit for providing a regulated output voltage is provided. The voltage regulator circuit includes an error amplifier configured to provide a control signal based on at least a portion of a fed-back output voltage and a reference voltage. A first output stage is configured to operate at a first supply voltage and provide the regulated output voltage based on the control signal. At least one second output stage configured to operate at a second supply voltage different from the first supply voltage and provide the regulated output voltage based on the control signal. A switch-over unit is configured to switch over the control signal between the first output stage and the second output stage. |
