Abstract

Die erfindungsgemäße Schaltung zur Spannungsversorgung weist einen ersten Versorgungsspannungseingang (IN1) auf, welcher mit einem ersten Komparator (CMP1) und einem ersten Span-nungsregler (REG1) verbunden ist, wobei der erste Komparator (CMP1) den ersten Spannungsregler (REG1) steuert. Weiterhin ist ein zweiter Versorgungsspannungseingang (IN2) vorgesehen, welcher mit einem zweiten Komparator (CMP2) und einem zweiten Spannungsregler (REG2) verbunden ist, wobei der zweite Kompa-rator (CMP2) den zweiten Spannungsregler (REG2) steuert. Schließlich ist ein Versorgungsspannungsausgang (O) vorgese-hen, welcher mit den Ausgängen der beiden Spannungsregler (REG1, REG2) verbunden und auf die beiden Komparatoren (CMP1, CMP2) rückgekoppelt ist.
