    Abstract: A regulating system comprising: an input terminal (K10) for applying an input voltage (Vin), an output terminal (K20) for providing an output voltage (Vout) and an output current (Iout), a semiconductor element (Q1) regulating the output voltage (Vout), which element has a load path which is connected between the input terminal (K1) and the output terminal (K2), and a control input to which a regulating signal (Ib1) is applied, a regulating signal generation circuit to generate the regulating signal (Ib1), which circuit has a current mirror arrangement (Q2, Q3) including a first and second current mirror path, wherein a controlled current source (Q4) is connected in series to the first current mirror path, which source induces a first current dependent on one of the output signals (Vout) in the first current mirror path, and wherein a second current (12) through the second current mirror path is dependent on the first current (I1), a splitter circuit (20) which conducts the second current (I2) to the output terminal (K2) or to a reference potential (GND), dependent on a load path voltage (Vec1) applied over the load path of the semiconductor element (Q1).

    Abstract: A power switch circuit for driving an airbag squib module comprises a power transistor (110), a pre-charge capacitance (120) for storing a charge, a charging circuit (140) and a controllable energy-coupling element. The power transistor (110) has a first electrode (E1), a second electrode (E2) and a control electrode. A path between the first electrode (E1) and the second electrode (E2) is connected in series with the airbag squib module (120) between a supply potential (V SUP ) and a reference potential (V REF ). The charging circuit (140) charges the pre-charge capacitance (130) and the charging circuit (140) is therefore coupled with the pre-charged capacitance (130). The controllable energy coupling element (134) is connected between a first electrode of the pre-charge capacitance (130) and the control electrode (control) of the power transistor (110). The inventive power switch exhibits a high degree of stability, allows a fast switching of the power transistor (110) and further comprises an advantageous transient response.
