3V Current source with low voltage drop
that regulator has low drop out, but it requires a supply voltage for the internal circuitry (not for the load) thats a 1.5V more than the output voltage.  configure it as a current sink.


connect the load between +3V and in
connect Vcontrol to +3V
connect set to 31K resistor to ground
connect out to 3.3 ohms resistor to ground
