Abstract
A power supply with and input and output includes an amplifier configured to set an output voltage of the power supply output equal to a fixed input voltage for the power supply. The power supply has a first output stage coupled to the amplifier and configured to source and sink current at the output of the power supply between a first voltage rail and a third voltage rail. The power supply has a second output stage coupled to the amplifier and configured to source and sink current to the output of the power supply between a second voltage rail and the third voltage rail. A selection device is configured to enable the first and second output stages based on a selection input signal. The selection device is situated outside of the first and the second output stages.
