L7809CV-DG
by ST(意法半导体)
A fixed positive supply rail is the intended job of ST's L7809CV-DG linear regulator. As a member of the L78 family, it regulates a higher input supply down to a fixed output, with power dissipation influencing placement and thermal planning. The through-hole TO-220-3 package provides the physical format for this library entry. In real designs, 2 ProtoFlow engineers have used this conversion. Downloadable assets include a 3-pin KiCad symbol, the TO-220-3_L10.0-W4.5-P2.54-L footprint with 3 pads, and a 3D model that supports package-clearance review. This regulator can be opened directly in ProtoFlow for integration into a power-supply design.
