A power supply arrangement (10) comprises a voltage regulator (11), a driver circuit (28), and a control circuit (32). The voltage regulator (11) has a voltage regulator input (12) for the feeding of an input voltage (VIN), a voltage regulator output (13) to which an electrical load (20) is coupled that comprises a current source (21), a feedback input (14), and a comparator (15) that is coupled at a first input to the feedback input (14). The driver circuit (28) has a driver output (30) that is connected to a control terminal of the current source (21). The control circuit (32) comprises a control comparator (33) that is coupled at a first input with a signal output (44) of the driver circuit (28) and at an output with the feedback input (14) and also to which, at a second input, a reference signal (SR) can be fed. |
