ht7333-1.lbr	rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 2 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray	1mo ago

HT7333-1

HXY MOSFET · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

HT7333-1 from HXY MOSFET, in a SOT-89. 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 for the regulator. Connect to system ground; place input and output decoupling caps' return leads close to this pin.
2	VIN	power_in	Unregulated supply input, -0.3V to +18V absolute max. Recommended operating VIN ≥ 4.3V for 3.3V output with 40mA load. Bypass to GND with a capacitor placed close to the pin.
3	VOUT	power_out	Regulated 3.3V ±2% output (3.201-3.399V). Sources up to 250mA. Requires an output capacitor >2.2µF to GND (tantalum recommended) for loop stability via ESR-based compensation.

3D model: SOT-89 (KiCad packages3D, STEP)
3D model files: ht7333-1-etched.step / ht7333-1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht7333-1.step / ht7333-1.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ht7333-1.step`	57 KB	You want the bare part, or you mark your own boards.
`ht7333-1-etched.step`	1.0 MB	You want the part with `HT7333-1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 296 faces against 42 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.
