Is there a KiCad symbol and footprint for the ST1S12GR?
Yes. The symbol is EasyEDA_Cloud:ST1S12G12R and the footprint Package_TO_SOT_SMD:TSOT-23-5, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ST1S12GR?
TSOT-23-5, with 5 pins. Its footprint is drawn on this page.
Where is the ST1S12GR datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the ST1S12GR?
JLCPCB lists it as part C222072, with 1,251 in stock; the sellers' links on this page open their listings.
What can replace the ST1S12GR?
Parts like it in the library: the MT3540-F23 by XI'AN Aerosemi Tech, the TLV62569DBV by Texas Instruments, the SY8088IAAC by 矽力杰silergy and the MT3406 by XI'AN Aerosemi Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the ST1S12GR?
2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
