LM337TG

by onsemi(安森美)

A regulated negative supply rail is the main application for onsemi's LM337TG. This adjustable linear regulator belongs to the LM337 family and uses an external resistor network to set the output, making it useful in analog supplies and circuits requiring a negative rail. The TO-220-3 through-hole package is represented by a three-pin symbol and the three-pad footprint TO-220-3_L10.0-W4.5-P2.54-L. Both are included in the free KiCad download alongside a 3D model for checking the board assembly visually. The files come from a real ProtoFlow import, converted and checked in the editor. Open the LM337TG directly in ProtoFlow for use in your power circuit.
