hey , this is my circuit i want to get a range of voutput voltage from -12V to -9V , the load is potentiometer of 100ohm , i pur in serios a resistor of 25ohm
because i dont want to get infinite current , so in my simulation i cant get this range in the two cases(Rmin/Rmax) i get almost the same voltage -9V
