LM317T
by ST(意法半导体)The ST LM317T is an adjustable voltage regulator used where a circuit needs a regulated output set by external components. This through-hole version has three connections, so the symbol maps three pins to three pads. The free KiCad download includes that symbol, the TO-220AB-3_L10.4-W4.6-P2.54-T footprint, and a 3D model for checking its placement in a board assembly. Its package makes the regulator a distinct mechanical item to account for during layout. The conversion has been used by 2 ProtoFlow engineers in real designs. You can open the part directly in ProtoFlow.
