LM317 pins short circuited

[Xenon Photon]

Thank you very much everybody it is now working. the same circuit but better quality IC. I had to travel 50KM to the Cairo the capital of Egypt to just buy this IC.

Here the photo you can find the difference.
also do u think the IC from Cairo is original or high copy?

Middle and right are fakes, the left one is a possible real product.

Just so I get this straight, R1 = 120 ohm should guarantee at least 10 mA load. But how can that work with a pot R2 of up to 5 kohms? 37 V / 5120 ohm = 7 mA (and that's best case scenario, with lower input voltage you wouldn't even be able to get 7 mA)

R1 = 120 ohm will mean that the regulator circuit itself will draw at least 10mA (vref/R1 = 1.2/120 = 10mA) if however you have a load drawing 10mA already (such as an indicator LED) then R1 can be a higher value.
