摘要： A circuit arrangement in which the temperature dependency of the short-circuit current and/or the influence of the output signal by the load current are at least partially avoided has first and second input connections, first and second output connections, a supply voltage connection as well as with a voltage-controlled voltage source, an output stage and a short-circuit protective circuit, whereby the output signal from an input voltage applied to input connections is generated via voltage-controlled voltage source and output stage. The circuit arrangement is characterized in that a voltage sequencing circuit and a shunting resistor connected in parallel to voltage sequencing circuit are part of the short-circuit protective circuit and in that a parallel circuit formed of the voltage sequencing circuit and a shunting resistor is connected to the second output connection and second input connection.
