Is there a KiCad symbol and footprint for the LM2576-12BT?
Yes. the footprint Package_TO_SOT_THT:TO-220-5_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM2576-12BT?
TO-220-5, with 5 pins. Its footprint is drawn on this page.
Where is the LM2576-12BT datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the LM2576-12BT?
JLCPCB lists it as part C7216538, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM2576-12BT?
Parts like it in the library: the LM2576HVT-12G by HANSCHIP semiconductor, the LM2576HVT-12 by HGSEMI, the LM2576T-12 by HGSEMI and the LM2576HVT-12-TD by TDSEMIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
