TPTLV70033DCKR from TECH PUBLIC, in a SC-70-5. 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 pin, 1.2 V to 5.5 V operating range (absolute max -0.3 V to 6.5 V). Bypass with 1 uF to 10 uF ceramic to GND close to the pin.
2	GND	power_in	Device ground return for both the reference and the pass-transistor sense path.
3	EN	input	Active-high enable input. VENH >= 0.5 V (typ 0.7 V) turns the regulator on; VENL <= 0.85 V (typ 0.65 V) puts the device in shutdown (~0.1 uA). Do not float; absolute max -0.3 V to 6 V referenced to GND.
4	NC	unconnected	No internal connection. May be left floating or tied to GND for improved PCB layout robustness.
5	VOUT	power_out	Regulated 3.3 V output, up to 300 mA. Requires a 1 uF to 10 uF ceramic output capacitor to GND for stability. When EN is low, VOUT is actively discharged through an internal ~80 Ω resistor.

CAD (KiCad official)

3D model: SC-70-5 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tptlv70033dckr.step`	87 KB	You want the bare part, or you mark your own boards.
`tptlv70033dckr-etched.step`	2.4 MB	You want the part with `TPTLV70033DCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 595 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.
