Boards in 1 GitHub repository, designed in KiCad, that use the LM337IMP by Texas Instruments (0.003%Vout 0℃~+125℃@(Tj) 1 1.25V~37V 1.5A 40V 77dB@(120Hz) Adjustable Negative Over Current Protection、Over Temperature Protection、Short Circuit Protection SOT-223-4 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS). See how each wires it, with its parts, size, README and files; the LM337IMP’s symbol, footprint and pinout are on its own page.
