LM2576HVR-5.0 from HTC Korea TAEJIN Tech, in a TO-263-5. 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	VIN	power_in	Input supply voltage. Operating range up to 60V (absolute max 63V). Should be bypassed with a 100uF aluminum electrolytic capacitor close to the pin.
2	VOUT	output	Switch output. Internal power switch emitter/drain; connects to the catch diode cathode and the inductor. Fixed 5.0V regulated output for the -5.0 variant, delivered after the LC filter. Guaranteed 3A load current.
3	GND	power_in	Device ground. Single-point ground return for the input capacitor, output capacitor, catch diode, and feedback network. On the TO-263 package this pin is also the tab (thermal pad) and must be connected to ground.
4	FB/ADJ	input	Output voltage feedback / adjust pin. For the fixed 5.0V version, connect directly to the regulated output node (post-inductor). Internal reference is 1.23V; feedback bias current typically 50nA (max 500nA).
5	ON/OFF	input	Active-low shutdown input (TTL-compatible). Logic low (VIL <= 1.2V typ, 0.8V over temp) enables the regulator; logic high (VIH >= 2.2V, 2.4V over temp) puts the device in standby (typ 50uA at VIN=60V). Tie to GND for always-on operation.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lm2576hvr-5-0.step`	180 KB	You want the bare part, or you mark your own boards.
`lm2576hvr-5-0-etched.step`	2.0 MB	You want the part with `LM2576HVR-5.0` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 556 faces against 135 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
