Abstract

Die Erfindung betrifft einen Parallelspannungsregler mit einem steuerbaren Lastelement (MN2), das mit den Ausgangsklemmen des Parallelspannungsreglers verbunden ist, und eine Referenzspannungsquelle (VREF) zur Festlegung der Sollausgangsspannung. Der erfindungsgemäße Parallelspannungsregler ist dadurch gekennzeichnet, daß eine schnelle Regelung über zwei Stromspiegel (5, 6) erfolgt, wobei der erster Stromspiegel (5) mit der Referenzspannungsquelle (VREF) im Steuerzweig des ersten Stromspiegels (5) liegt, der gesteuerte Zweig des ersten Stromspiegels (5) einerseits mit der Ausgangsspannung (VOUT) und andererseits mit dem Steuerzweig des zweiten Stromspiegels (6) verbunden ist und das steuerbare Lastelement (MN2) durch den gesteuerten Zweig des zweiten Stromspiegels (6) gebildet ist.

The invention relates to a parallel voltage regulator with a controllable load element (MN2), which is connected to the output terminals of the parallel voltage regulator, and a reference voltage source (V REF ) for determining the target output voltage. The parallel voltage regulator according to the invention is characterized in that rapid regulation takes place via two current mirrors (5, 6), the first current mirror (5) with the reference voltage source (V REF ) being in the control branch of the first current mirror (5) and the controlled branch of the first Current mirror (5) is connected on the one hand to the output voltage (V OUT ) and on the other hand to the control branch of the second current mirror (6) and the controllable load element (MN2) is formed by the controlled branch of the second current mirror (6).
