VRH4801NTX from AnaSem, in a SOT-23-5. 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	Voltage input. Operating range 1.6V to 6.0V (absolute max -0.3V to +7.0V). Decouple to VSS with a ≥1.0µF ceramic capacitor close to the pin.
2	VSS	power_in	Power ground / negative supply return for the regulator and all internal circuitry.
3	EN	input	Chip enable (On/Off). VENH ≥ 1.2V enables the regulator; VENL ≤ 0.3V disables it and triggers CL auto-discharge (RDIS typ. 160Ω). EN input current ≈0.25~5µA at VEN=VIN=5V. Do not leave floating.
4	NC	unconnected	No internal connection (open). Leave floating or tie to a copper island; do not use as a routing via.
5	VOUT	power_out	Regulated output, factory-trimmed to 4.80V ±1% (Iout=30mA). Maximum output current 250mA, current limit typ. 300mA. Requires a ≥1.0µF ceramic output capacitor (CL) to VSS for phase compensation. Must not exceed VIN+0.3V to avoid parasitic-diode conduction into VIN.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`vrh4801ntx.step`	85 KB	You want the bare part, or you mark your own boards.
`vrh4801ntx-etched.step`	1.7 MB	You want the part with `VRH4801NTX` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 427 faces against 102 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.
