Is this a common failure mode of the LM317? I tried the simple 1 resistor CC circuit and also got about 7 mA no matter what. To be fair, I'm pretty sure all three of these LM317's have been soldered in backwards before in other circuits... I'm not good when it comes to checking the orientation.
EDIT: I'd appreciate it if someone built a simple CC circuit with a 47 ohm resistor and used a 1k resistor as the load. What voltage do you get across the 1k? current through it? I should be getting 26 volts (higher than my supply voltage) instead of 4 volts, and 26 mA instead of 4 mA.
FWIW: with adjust grounded, I get 640mV on the output. Not good?
