QSI PS1 voltage regulator replacement

Jeff_the_Coaster_GuyOGR Forum Member SUPPORTING MEMBERDIGITAL SUBSCRIBER

So I broke off one of the voltage regulators that doubles as a mounting post on one of my PS1 Boards. Trying to find a replacement.

This is the one I'm replacing:

It says LM337T P+

Does the "P+" indicate positive polarity? Because all of the replacements I'm finding are described as negative polarity.

Here are some of the parts I found on mouser. Would any of these be appropriate?

The component logo is "National Semiconductor. The "P+" indicates additional factory testing/quality or specifications such as special environment (Space/Military/etc). Digikey or Mouser has replacements.

Your Mouser link is good. Pick one that’s in stock of course. The TI looks good.
