Is there a KiCad symbol and footprint for the L6983N33Q?
Yes. The symbol is EasyEDA_Cloud:L6983N33QTR and the footprint EasyEDA_Cloud:TQFN-16_L3.0-W3.0-P0.50-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the L6983N33Q?
TQFN-16-EP(3x3), with 17 pins. Its footprint is drawn on this page.
Where is the L6983N33Q datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the L6983N33Q?
JLCPCB lists it as part C509132, with 0 in stock; the sellers' links on this page open their listings.
What can replace the L6983N33Q?
Parts like it in the library: the LM2596S-3.3(UMW) by UMW, the LM2596S-3.3 by GR, the LM2596R-3.3 by HTC and the XL2596S-3.3E1 by XLSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
