I'm using this 1.2 V voltage regulator and having some serious problems.
Currently have +5 V going to EN and IN pins and GND is connected to GND, seeing ~1.6 V on OUT pin when connecting it to GND through 8k resistor.
I have been trying to figure out why the regulator is not outputting 1.2 V for days now and I am completely stumped.
Any ideas?

These devices need input and output capacitors to keep them stable. Take a look at the datasheet:
Without local caps (as close as possible to the pins) these things can and will oscillate, which unless you're looking with a scope can appear as incorrect DC voltage levels.
Add caps and try again. If you're still not having any luck post some scope shots of the input and output voltages.
