TPTLV70033DDCR 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	Input supply voltage. Operating range 1.2V to 5.5V (absolute max 6.5V to GND). Bypass with a 1µF to 10µF ceramic capacitor close to the pin.
2	GND	power_in	Device ground reference and return path for the regulator. Typical ground/quiescent current is 20µA at no load.
3	EN	input	Enable control input. Drive above VENH (typ 0.7V, max 0.9V) to enable the regulator; drive below VENL (typ 0.65V, min 0.4V) to shut down. Absolute max 6V to GND; input leakage ~0.1µA at 5.5V. Do not leave floating.
4	NC	unconnected	No internal connection. Leave floating or tie to GND on the PCB.
5	VOUT	power_out	Regulated output of the LDO. Fixed 3.3V (this ordering suffix) at up to 300mA, ±1.5% accuracy. Requires a 1µF to 10µF ceramic output capacitor. Includes an internal ~80Ω active-discharge path to GND when disabled.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tptlv70033ddcr.step`	85 KB	You want the bare part, or you mark your own boards.
`tptlv70033ddcr-etched.step`	2.3 MB	You want the part with `TPTLV70033DDCR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 574 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.
