In a bipolar regulated power supply, two pass devices (transistors) are connected in a complementary symmetry circuit, one controlling the current from a positive voltage source and the other the current from a negative voltage source. One pass device connected in a first control loop is controlled by a source of input signals and feedback from the output terminal. A second control loop maintains a constant quiescent current in the two pass devices. In order to maintain this quiescent current in the presence of load current, a second feedback to the second loop, sensing load current, is provided.
