Is there a KiCad symbol and footprint for the LM337T?
Yes. The symbol is dk_PMIC-Voltage-Regulators-Linear:LM337T_NRND and the footprint digikey-footprints:TO-220-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM337T?
TO-220, with 3 pins. Its footprint is drawn on this page.
Where is the LM337T datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM337T?
JLCPCB lists it as part C2869423, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM337T?
Parts like it in the library: the L7805CV by STMicroelectronics, the L7805CV-DG by STMicroelectronics, the L7805CV(XBLW) by XBLW and the LM317T by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LM337T?
7 boards in 7 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
