Abstract
A voltage regulator operable to selectively supply an extended range of regulated voltages by using multiple levels of unregulated voltages and a single amplifier. The voltage regulator is coupled to a plurality of passing elements in parallel via enabling switches. Each passing element is configured to receive a respective level of unregulated voltage and, when enabled, can pass current to the voltage regulator and thereby induce a corresponding level of regulated voltage at the output terminal of the voltage regulator. To output a specific regulated voltage, the voltage regulator can operate in a single passing mode in which only the passing element receiving the corresponding unregulated voltage is enabled to pass current. Alternatively, in a parallel passing mode, two or more passing elements receiving different levels of unregulated voltages can be enabled to pass current.
