ABSTRACT:
An integrated electronic device includes circuitry for providing a regulated output supply voltage level at an output node from an adjustable current. The circuitry includes an adjustable current source for providing the adjustable current and for adjusting the adjustable current to a magnitude of a target value in response to a configuration signal, an auxiliary adjustable current source providing an auxiliary adjustable current having a magnitude corresponding to the target value, and an output supply voltage level regulating loop coupled to the output node and adapted to keep the output supply voltage level at a preset value. A current selecting stage is adapted to receive the adjustable current and the auxiliary current. The current selecting stage is further adapted to supply a selected current corresponding to a lesser value of the adjustable current and the auxiliary adjustable current. Further, a current limiting stage is coupled to the output node for limiting the selected current to a predefined magnitude.
