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.
