Damaged OLED LCD voltage regulator replacement
Easiest to just replace it with the component you removed unless there's something else that makes more sense based on how you damaged it?
Schematic calls out a XC6206P332MR-G which outputs 3.3V based on a ~5V input. Were you trying to use this with a 12V supply when you broke it?
If you have another good source of 3.3V somewhere in your project you might not even need the voltage regulator so you'd just desolder and pump in 3.3V from that 3.3V supply to the desoldered pin where you need it.
