Overview

The L7980 is a DC DC Converter made by STMicroelectronics in a VFQFPN-8(3x3) package with 9 pins. -40℃~+150℃ 1 2.4mA 250kHz~1MHz 2A 4.5V~28V 600mV~28V Adjustable Buck Buck Built-in No VFQFPN-8(3x3) DC-DC Converters ROHS.

PCBKit's library has its KiCad symbol (EasyEDA_Cloud:L7980TR, from EasyEDA) and its footprint (EasyEDA_Cloud:SON-8_L3.0-W3.0-P0.50-BL-EP, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C2826414). 5 open-source boards in 5 repositories on GitHub use it.
