Is there a KiCad symbol and footprint for the AX5201ESA?
Yes. The symbol is EasyEDA_Cloud:AX5201ESA and the footprint EasyEDA_Cloud:SOP-8_L4.9-W3.9-P1.27-LS6.0-BL-EP-2, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the AX5201ESA?
SOP-8-EP, with 9 pins. Its footprint is drawn on this page.
Where is the AX5201ESA datasheet?
Axelite Tech publishes it: the Datasheet link on this page opens it.
Where can I order the AX5201ESA?
JLCPCB lists it as part C211668, with 0 in stock; the sellers' links on this page open their listings.
What can replace the AX5201ESA?
Parts like it in the library: the LM5013DDA by Texas Instruments, the LMR38020FDDA by Texas Instruments, the SSP9461 by Shanghai Siproin Microelectronics and the LMR38020SDDA by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
