Abstract: A circuit arrangement comprises a load current controller (10a) and a monitoring device (11a, 11b). The load current controller (10a) has its input side connected to a first reference signal connection (A6) and a load reference connection (A2), the latter being able to be coupled to an output of the current source (SQn) and being designed to provide a control signal (IB) at an output which is coupled to a control connection (A1) for controlling the current source (SQn). The control signal (IB) is determined on the basis of a comparison of a load current (IL) with a first reference signal (IL-REF, IREF, VREF). The monitoring device (11a, 11b) has its input side coupled to the output of the load current controller (10a) and to one of the inputs of the load current controller (10a). The monitoring device (11a, 11b) is designed to provide a feedback signal (RS) at an output coupled to the feedback connection (A3) on the basis of a comparison of the control signal (IB) with the load current (IL). The feedback connection (A3) provides an external feedback signal (ERS) for adjusting a load voltage (VL) which drops across the current source (SQn) and the load (LK) coupled thereto.
