A low-dropout regulator comprises an output current branch () in which a first output driver () and a second output driver () is arranged. An input amplifier stage () provides a first control current (I) to control the operating state of the first and the second output driver (). A current generator unit () provides a second control current () to operate the first output driver () in the second operating state and provides a third control current () to operate the second output driver () in the second operating state, when the first control current (I) of the input amplifier stage () is below a threshold level.

Low-dropout regulator having sourcing and sinking capabilities

A voltage regulator, comprising: an input terminal; an output terminal at which an output voltage is provided; an output transistor which couples the input terminal of the voltage regulator to the output terminal of the voltage regulator; and a transimpedance amplifier including an input terminal which is coupled to the output terminal of the voltage regulator and an output terminal which is coupled to a control terminal of the output transistor, optionally via a coupling, the coupling having an impedance value between the output terminal of the transimpedance amplifier and the control terminal of the output transistor which at a given frequency is smaller than or equal to an impedance value of an output impedance of the transimpedance amplifier.
