High speed regulator with low capacitor values

Abstract

The present document relates to voltage regulators. In particular, the present document relates to a method and a corresponding voltage regulator with improved performance subject to load transients. A regulator configured to provide a load current at an output voltage in dependence of an input voltage is described. The regulator comprises a core regulator configured to provide a core current at a core output voltage in dependence of the input voltage. Furthermore, the regulator comprises current sensing means configured to provide an indication of the core current. The output voltage is dependent on the core output voltage and on a voltage drop at the current sensing means. In addition, the regulator comprises a current source configured to provide an auxiliary current based on the indication of the core current. The load current is dependent on the core current and on the auxiliary current.

Dependencies are inferred from the claim text.
