Abstract
A power supply includes an input terminal, an output terminal, a DC voltage regulator coupled between the input terminal and the output terminal to provide a substantially constant DC output voltage at the output terminal, a voltage divider coupled between the output terminal and ground (e.g., earth ground or another suitable reference potential), the voltage divider including at least a first resistance, a second resistance and a first node between the first resistance and the second resistance, the first node coupled to the DC voltage regulator to provide a feedback voltage to the DC voltage regulator for regulating the DC output voltage, and an adjustable shunt regulator coupled between the output terminal and the first node.
