It is shown how a low‐voltage regulated power supply, which can operate from a limited supply voltage of 6 V or less, can be designed making use of a silicon‐germanium transistor pair as voltage reference element in a novel circuit configuration. Pair selection efforts are not required, and the temperature coefficient can be assigned beforehand through design calculations and a single output voltage adjustment. The circuit example shown is able to function with an input‐output voltage differential of only a few tenths of a volt and its temperature compensation is effective between − 30° and + 85°C.
