Questions
Is there a KiCad symbol and footprint for the LM1771SMM?
Yes. The symbol is EasyEDA_Cloud:LM1771TMM_NOPB and the footprint Package_SO:VSSOP-8_3x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM1771SMM?
VSSOP-8-0.65mm, with 8 pins. Its footprint is drawn on this page.
Where is the LM1771SMM datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM1771SMM?
JLCPCB lists it as part C1880382, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM1771SMM?
Parts like it in the library: the LM3478QMMX by Texas Instruments, the LM3489QMMX by Texas Instruments, the LM5085MM by Texas Instruments and the UCC28C44DGK by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
