Questions
Is there a KiCad symbol and footprint for the A7985A?
Yes. The symbol is EasyEDA_Cloud:L7980TR and the footprint EasyEDA_Cloud:HSOP-8_L5.0-W4.0-P1.27-LS6.2-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the A7985A?
SOIC-8, with 9 pins. Its footprint is drawn on this page.
Where is the A7985A datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the A7985A?
JLCPCB lists it as part C2926948, with 5,115 in stock; the sellers' links on this page open their listings.
What can replace the A7985A?
Parts like it in the library: the LMR14020SDDAR by Texas Instruments, the L5973D013 by STMicroelectronics, the TPS54327DDAR by Texas Instruments and the L5973ADTR by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
