Abstract: A regulator includes a first controllable semiconductor component, which has an input terminal connected to a regulator input, an output terminal connected to a regulator output, and a control terminal. A second semiconductor component is provided, which is connected to the control terminal of the first semiconductor component and has an input terminal, an output terminal and a control terminal. A comparison device that has a first input, a second input and an output connected to the control terminal of the second semiconductor component is further provided. A reference voltage can be applied to the first input of the comparison device and the second input is connected to the regulator output. A driver device, which, when a predetermined threshold value is exceeded by an input signal present at the regulator input, diverts part of the current from the control terminal of the first semiconductor component to the regulator output.

Abstract: The current-voltage regulator has a reference voltage source with an output. Two transconductance amplifiers each have two inputs and a current output. The current outputs of the transconductance amplifiers are coupled to one another and form an output of the current-voltage regulator. One of the inputs of the transconductance amplifiers is coupled to the output of the reference voltage source, and the other inputs of the transconductance amplifiers are driven, respectively, by a current sensor signal and a voltage sensor signal.

Abstract: A circuit configuration for protecting an integrated circuit from damage by a voltage present at an output exceeding the supply voltage range of the integrated circuit includes a given number of parasitic circuit structures of the integrated circuit. Additional circuit structures combined with the parasitic circuit structures form a protective circuit. The circuit structures are activated by the voltage at the output to become operative for protection.

Abstract: An integratable circuit configuration includes a first transistor of one conduction type having an emitter being acted upon by a first potential, a collector being acted upon by a second potential, a base, a base-to-collector path and a base-to-emitter path. A resistor is connected in parallel with the base-to-emitter path of the first transistor. A second transistor of the other conduction type is connected to the base of the first transistor for triggering. A diode may be connected in parallel with the base-to-collector path of the first transistor. The diode conducts in inverse operation for reverse current reduction during inverse operation of the first transistor. A third transistor may be connected to the first transistor instead of the diode and fourth and further transistors may also be connected to the first transistor.
