Overview
The LM5109SD is a MOSFET made by Texas Instruments in a WSON-8(4x4) package with 9 pins. -40℃~+125℃ 100V 1A N-Channel WSON-8(4x4) MOSFETs ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:LM5109SD_NOPB, from EasyEDA) and its footprint (EasyEDA_Cloud:WSON-8_L4.0-W4.0-P0.80-TL-EP, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C3276801).
