ABSTRACT:
An integrable shunt regulator includes two connection terminals to be connected between poles of a supply voltage source. A controllable semiconductor component has a control input and a load path connected to the two connection terminals. A differential amplifier has first and second inputs and an output connected to the control input of the controllable semiconductor component. First and second transistors have emitter terminals and interconnected base and collector terminals connected to one of the connection terminals. A first resistor is provided. The emitter terminal of the first transistor is connected to the first input of the differential amplifier and is connected through the first resistor to the other of the connection terminals. A series circuit of second and third resistors has a connection node connected to the second input of the differential amplifier. The emitter terminal of the second transistor is connected through the series circuit of the second and third resistors to the other of the connection terminals.
