GM7333TB from GATEMODE GM7333, in a SOT-89-3. 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	OUT	power_out	Regulated 3.3V output pin. Requires a ceramic output capacitor (≥1.5µF effective for VOUT ≥2.5V, ESR 0Ω-0.2Ω) for stability; supplies up to 200mA continuous, current-limited at 250-300mA.
2	GND	power_in	Ground reference pin. Connect directly to the PCB ground plane. On SOT-89-3 this pin is fused to the package tab for improved thermal dissipation (θJA = 63°C/W).
3	IN	power_in	Input voltage pin. Recommended operating range 4.5V-40V (absolute max 45V). A 0.1µF to 2.2µF ceramic decoupling capacitor to GND is recommended for input noise filtering and transient response.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`gm7333tb.step`	57 KB	You want the bare part, or you mark your own boards.
`gm7333tb-etched.step`	1.3 MB	You want the part with `GM7333TB` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 350 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.
