Is there a KiCad symbol and footprint for the LM3102MH?
Yes. The symbol is EasyEDA_Cloud:LM3102QMHX_NOPB and the footprint EasyEDA_Cloud:HTSSOP-20_L6.5-W4.4-P0.65-LS6.4-BL-EP-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM3102MH?
HTSSOP-20-EP, with 21 pins. Its footprint is drawn on this page.
Where is the LM3102MH datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM3102MH?
JLCPCB lists it as part C1355323, with 70 in stock; the sellers' links on this page open their listings.
What can replace the LM3102MH?
Parts like it in the library: the LM5576Q0MHX by Texas Instruments, the LT3501IFE#TRPBF by Analog Devices, the LM26003QMH by Texas Instruments and the LM5005MH/NOPB by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LM3102MH?
