Is there a KiCad symbol and footprint for the LM2575-3.3BT?
Yes. The symbol is Regulator_Switching:LM2575-3.3BT and 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 LM2575-3.3BT?
TO-220-5, with 5 pins. Its footprint is drawn on this page.
Where is the LM2575-3.3BT datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the LM2575-3.3BT?
JLCPCB lists it as part C7216536, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM2575-3.3BT?
Parts like it in the library: the LM2575HVT-3.3G by HANSCHIP semiconductor, the LM2575T-3.3G by HANSCHIP semiconductor, the LM2576T-3.3 by HGSEMI and the LM2575HVT-3.3 by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LM2575-3.3BT?
