I need the name of the sop8 integrated circuit. The ST logo on it says ua gb145. The 8th leg is +12 volt input. The 7th leg is gnd. The 3rd leg is 2t1 smd push button. The 1st leg is out +12. Can you tell me what this integrated circuit is?

Welcome @Volkann, to the community!

The 2nd line here contains the date code, the marking is at the 1st line, here ending with UA.

Please try to recognize the letters/numbers at the beginning of the first line.

Regards
/Peter

Thanks for the answer but the numbers and letters before ua have been deleted. I searched a lot but couldn't find anything. If you know this integrated circuit, please help.

You'd need an example that was legible. If this one has exploded or vented magic smoke it's going to be near impossible without a schematic or portion of one.

Could try acetone or other methods to inspect or light the part to see or raise the marks.

Might be easier to find someone with a working unit.
