Unlikely. Have you measured the voltage present at Vin?

Yes, I measured across ground and Vin and it shows ~4V. Across ground and Vout 0V.

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.
