Abstract
A current-supply circuit includes a regulation transistor. The regulation transistor is formed to regulate, based on a first supply voltage present on a first supply-voltage feed line, a second supply voltage present on a second supply-voltage feed line. The regulation transistor provides a supply current to the second supply-voltage feed line. The voltage-supply circuit further includes an operating-point determiner, which is formed to determine, based on information that is a measure for the supply current, whether the regulation transistor is at a low operating point at which the supply current is below a determined current. The voltage-supply circuit further includes a preventer that is formed to prevent, starting from the low operating point, a rise of the supply current by at least a predetermined current amount from occurring within a predetermined period.
