Questions
Is there a KiCad symbol and footprint for the PM8903A?
Yes. The symbol is EasyEDA_Cloud:PM8903TR and the footprint EasyEDA_Cloud:VFQFPN-16_L3.0-W3.0-P0.50-TL-EP1.6, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the PM8903A?
VFQFPN-16(3x3), with 17 pins. Its footprint is drawn on this page.
Where is the PM8903A datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the PM8903A?
JLCPCB lists it as part C2071345, with 100 in stock; the sellers' links on this page open their listings.
What can replace the PM8903A?
Parts like it in the library: the ISL8025AIRTAJZ-T by Renesas Electronics, the L6738 by STMicroelectronics and the L6738A by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
