Hello all.
I recently copied one of my older designs with a TLV1117 ADJ with a pot. The old (working design) used one of the surface mount packages but for the new one I swapped to the TO-220 pack. I just got my pcbs built up and adjusting the pot has no affect on the output. The only thing I added was a protection diode from pins 2-3 but I tried removing it and still having issues. I checked that the pot is actually adjusting across its full range. I thought maybe my load was too light so I added a resistor to pull some current, that made no difference. The voltages out are about 1V below the input, like the device is just spitting out with the minimum dropout voltage. I attached the main power section of my circuit.
Any ideas would be great, I need this working asap.
