A voltage regulating arrangement in a television receiver for simultaneously regulating the low-voltage power supply and the horizontal deflection system with a single regulator circuit. The regulating arrangement utilizes the horizontal output transformer primary winding as a brightness-dependent variable impedance which, together with the low-voltage (24-volt) power supply load, forms a voltage dividing network between the high-voltage (B+) power supply and ground. A single shunt regulator is coupled across the low-voltage power supply load to insure that a constant potential is maintained at the junction of the variable impedance and the 24-volt load. The 24-volt load and its associated shunt regulator further combine to provide load regulation of the horizontal deflection system by presenting an impedance which varies in a directly proportional manner with impedance variations of the horizontal output transformer primary winding to maintain a relatively constant voltage thereacross.
