Abstract

A power providing circuit which is configured to provide a current at an output voltage to a load at an output of the power providing circuit is described. The power providing circuit comprises a power transistor which is configured to draw the current from a supply voltage, wherein a resistance of the power transistor is controlled using a control voltage which is applied to a control port of the power transistor. Furthermore, the power providing circuit comprises short circuit protection circuitry which is configured to couple the control port of the power transistor with a first port of the power transistor to put the power transistor in an off-state, subject to a drop of the output voltage.
