That is/was made by ON Semi(conductor). I'd contact them.I have a voltage regulator and I can't find a datasheet. Can someone help me?
Thanks
Mod: lightened your image.E.
Likely an in-house number.
It could be a MOSFET or a voltage regulator similar to one of these.

I will try that. Thank you.Trace the board and find out which pin is VIN and which is VOUT.
That will help with the search.
Comparing NCV8141 and NCV8361, pin-4 is GND on both.
