TPSP6201EM5-L-3-3 from TECH PUBLIC, 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	Regulator supply input, 1.2V to 5.5V (absolute max 6.5V). Bypass to GND with a 1-10µF ceramic or tantalum capacitor placed close to the pin.
2	GND	power_in	Device ground return for the internal reference, error amplifier and pass FET. Typical GND current is ~6µA at no load.
3	CE	input	Chip enable (active-high). Drive above VIH=1.0V to enable the regulator; drive below VIL=0.4V (or to GND) to shut down (ISD ~0.1µA, VOUT is actively discharged through ~100Ω). Input current ~10nA at VEN=5V. Do not leave floating.
4	NC	unconnected	No internal connection. Leave floating or tie to GND for mechanical stability.
5	OUT	power_out	Regulated output, fixed 3.3V ±2% for the -3-3 option, up to 200mA (typical current limit 500mA). Requires a 1-10µF ceramic or tantalum output capacitor for stability; dropout ~0.18V at 300mA (VOUT≥3V).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tpsp6201em5-l-3-3.step`	85 KB	You want the bare part, or you mark your own boards.
`tpsp6201em5-l-3-3-etched.step`	2.7 MB	You want the part with `TPSP6201EM5-L-3-3` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 659 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.
