LM1086T-5.0 from HGSEMI, in a TO-220. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	GND	power_in	Ground reference pin for the fixed 5.0V version. On the adjustable version this pin functions as ADJ; on the LM1086T-5.0 fixed-output part it is tied internally to the feedback divider and used as the device ground return.
2	VOUT	power_out	Regulated 5.0V output. Delivers up to 1.5A continuous with 1.2V typical dropout. Requires an output capacitor (typ. 22µF tantalum) for stability; smaller values acceptable on fixed-output versions per datasheet.
3	VIN	power_in	Unregulated input supply. Recommended operating input up to 15V; absolute maximum 20V. For 5.0V output, VIN should be ≥6.5V to guarantee regulation over full load range. A 10µF input capacitor is recommended.
