Comment on No output with MCP1700-3302E

  Just to be sure: positive probe on Vin, negative probe on GND, measurement shows no minus sign?

    Yes, that’s what I did and what it shows. I also attached a picture of my test setup just in case I did something wrong there

      Huh, that’s weird. Double checking the part markings would’ve been my next suggestion, but the picture shows they’re correct. Maybe try a 1kOhm load resistor across Vout and GND, though in theory you should be able to see the output voltage without it.

        I tried with the resistor, same thing, 0V. I made two images showing the measurements Image Image
