I'm using the LT3086 as a linear postregulator to a switching power supply. I'm designing a circuit that acts like an adjustable power supply for a bench. I had planned on using LTC7106 to adjust the output voltage of the LT3086 and the switcher. If I were to inject more than 50uA into the SET pin, would I be able to drive the LT3086 output all the way down to 0V (given the appropriate current for the SET resistor)?
