I would like to get a datasheet for a ST Micro product, I have attached a photo of the device

It's an LD1085CD-TR in DPAK (TO252) which has been already discontinued.
There is still the LD1085D2TR in D2PAK (TO263), but due to the bigger package it is not a drop-in replacement.
Does this answer your question?

Just one other question, the regulator comes in different voltages, do I have the LD1085CDT which is an adjustable voltage output?

These both look to be a fixed voltage, you should check the south pad is ground, or goes to ground via a resistor. The one on the top side, doesn't look to be a divider, and this likely a standard voltage supply rather than something novel.

This looks to have been worked over several times, are you sure there isn't something else amiss with the circuit. Perhaps sketch out a schematic as you can discern it.
