Abstract
A voltage regulator having a current mirror for decoupling a partial current icluding a first NMOS transistor as a series transistor. In addition, the voltage regulator has a second NMOS transistor, which forms a current mirror with the first NMOS transistor. Furthermore, in the case of the voltage regulator, the first NMOS transistor is connected in series with a first PMOS transistor and a third transistor. The second NMOS transistor is likewise connected in series with a second PMOS transistor and a fourth transistor, the control inputs of the first and second PMOS transistors being connected to one another and the control inputs of the third and fourth transistors being connected to a control terminal for setting the magnitude of the partial current to be decoupled.
