Abstract
A shunt regulator circuit having a reference voltage generator in which the collector currents of a pair of transistors are adjusted by the ratios of their load resistances to produce a temperature coefficient equal and opposite to the temperature coefficient of third transistor; a proportional sample of the output voltage is compared to the temperature stable reference voltage to adjust the shunt current to maintain the output voltage constant.
