Questions

Is there a KiCad symbol and footprint for the LM337SP?

Yes. The symbol is EasyEDA_Pro:LM337SP and the footprint EasyEDA_Pro:to-220-3_l10.0-w4.5-p2.54-t, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM337SP?

TO-220, with 3 pins. Its footprint is drawn on this page.

Where is the LM337SP datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the LM337SP?

JLCPCB lists it as part C118272, with 168 in stock; the sellers' links on this page open their listings.

What can replace the LM337SP?

Parts like it in the library: the L7812CV by STMicroelectronics, the L7812ACV by STMicroelectronics, the L7905CV by STMicroelectronics and the L7805CP by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM337SP?

3 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
