If you are operating the unit below 255 µA in constant current mode, the output may become unregulated with the following load conditions:
The load resistance is <175 mΩ and the load inductance is >20 µH. If this occurs, an UNRegulated flag will be generated and the output current may rise
above the programmed value but will remain less than 255 µA.
