Is there a KiCad symbol and footprint for the LDL40PUR?
Yes. The symbol is EasyEDA_Cloud:LDL40PUR and the footprint EasyEDA_Cloud:WDFN-6_L2.0-W2.0-P0.65-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LDL40PUR?
DFN-6(2x2), with 7 pins. Its footprint is drawn on this page.
Where is the LDL40PUR datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the LDL40PUR?
JLCPCB lists it as part C41641376, with 88 in stock; the sellers' links on this page open their listings.
What can replace the LDL40PUR?
Parts like it in the library: the LTP8P45-50XF6/R6 by Linearin. Check their datasheets: a part that fits the footprint may still differ in its ratings.
