Need help finding replacement for "100N30" bjt, to-92

Thank you for any help you can provide.
I have an old power supply that I am troubleshooting, and one transistor appears faulty. I have tried to track down this transistor, with no success, so I cannot find a datasheet, nor can I cross-reference it.
The only marking on it (no manufacturer logo) is 100N30. It is a to-92 form factor.
Thanks again.

Thank you for contacting DigiKey , sorry I am not finding anything with those markings either .

Thanks Craig

I believe I mis-identified the component as a transistor in my original post, when in fact it is likely a voltage regulator.
Sorry for the confusion.

Thank you nonetheless for trying to find it.
