Is there a KiCad symbol and footprint for the L99ASC03G?
Yes. The symbol is EasyEDA_Cloud:L99ASC03 and the footprint EasyEDA_Cloud:TQFP-48_L7.0-W7.0-P0.50-LS9.0-BL-EP4.5, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the L99ASC03G?
TQFP-48-EP(7x7), with 49 pins. Its footprint is drawn on this page.
Where is the L99ASC03G datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the L99ASC03G?
JLCPCB lists it as part C2150702, with 0 in stock; the sellers' links on this page open their listings.
What can replace the L99ASC03G?
Parts like it in the library: the L99ASC03 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
