A current regulator arrangement for a laser diode arrangement, including a DC voltage source that provides an upper and a lower voltage level different than ground and at least one current regulator connected to the DC voltage source and having at least one transformer that is connected at the upper and lower voltage level. The current regulator arrangement further includes a current measuring device that senses an output current of the at least one current regulator and is connected to a control device that generates an actuation signal for the at least one transformer.
