Control circuitry for stabilizing a DC voltage outputted by a DC power supply against changes in ambient temperature. The control circuitry includes: measurement circuitry configured to output a measurement voltage representative of a DC voltage outputted by a DC power supply; reference circuitry configured to output a reference voltage; and comparison circuitry configured to compare the measurement voltage with the reference voltage and, based on the comparison, output a control signal for controlling the DC voltage outputted by the DC power supply. At least one temperature-sensitive component of the control circuitry is located in an enclosure configured to maintain a substantially constant temperature within the enclosure.
