Abstract

Die integrierte Schaltung weist einen Spannungsregler (OP) zum Erzeugen einer internen Versorgungsspannung (VInt) auf, der einen Eingang zum Zuführen eines Istwertes und einen Eingang zum Zuführen einer Referenzspannung (VRef) als Sollwert aufweist. Der Istwert wird mittels eines ersten Spannungsteilers (R3, R4) aus der internen Versorgungsspannung (VInt) erzeugt. Die Empfindlichkeit des Spannungsreglers (OP) hängt vom Widerstandswert wenigstens eines Widerstandselementes (R3) des ersten Spannungsteilers ab. Dem ersten Spannungsteiler (R3, R4) ist ein zweiter Spannungsteiler (R1, R2) parallel geschaltet, der das gleiche Spannungsteilerverhältnis wie der erste Spannungsteiler aufweist und der durch wenigstens ein Schaltelement (S1, S2) aktivierbar und deaktivierbar ist.

Figure 00000001
The integrated circuit has a voltage regulator (OP) for generating an internal supply voltage (V Int ), which has an input for supplying an actual value and an input for supplying a reference voltage (V Ref ) as a setpoint. The actual value is generated from the internal supply voltage (V Int ) by means of a first voltage divider (R3, R4). The sensitivity of the voltage regulator (OP) depends on the resistance value of at least one resistance element (R3) of the first voltage divider. A second voltage divider (R1, R2) is connected in parallel to the first voltage divider (R3, R4) and has the same voltage divider ratio as the first voltage divider and which can be activated and deactivated by at least one switching element (S1, S2).
