TMI6030-28 from TMI, 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 of the LDO. Operating range 2.5V to 5.5V (abs max 6V). Requires a ≥1µF ceramic bypass capacitor (X5R/X7R, 0402 or larger) placed close to the pin.
2	GND	power_in	Signal ground reference for the regulator.
3	EN	input	Active-high enable input. Drive ≥1.5V (VENH typ 1.0V, max 1.15V) to enable the regulator; ≤0.4V (VENL typ 0.75V) to shut down (shutdown current <1µA). Must not be left floating. Absolute max 6V.
4	NC	unconnected	No connection on the TMI6030-28 (2.8V fixed output) variant. The pin location is BP (bypass) on other fixed-output codes and FB on the adjustable version, but is unused on -28. Leave floating on the PCB.
5	VOUT	power_out	Regulated 2.8V output of the LDO, up to 300mA. Requires a 1µF-10µF low-ESR ceramic output capacitor (X5R/X7R, 0402 or larger) for stability. An internal ~130Ω discharge resistor pulls VOUT to GND when the device is disabled.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tmi6030-28.step`	85 KB	You want the bare part, or you mark your own boards.
`tmi6030-28-etched.step`	2.1 MB	You want the part with `TMI6030-28` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 498 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.
