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.
