TLV74328PDBVR from Texas Instruments, 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	IN	power_in	Input supply pin, 1.4 V to 5.5 V. Place a small (typ. 1-µF) ceramic capacitor from this pin to GND for stability and transient response.
2	GND	power_in	Device ground reference.
3	EN	input	Enable input. Drive EN above V_EN(HI) to enable the regulator; drive EN below V_EN(LO) to place the LDO in shutdown mode. EN input range is 0 V to VIN.
4	NC	unconnected	No internal connection. May be left floating or tied to any potential.
5	OUT	power_out	Regulated 3.3-V output pin, sources up to 300 mA. Use a 1-µF ceramic capacitor from this pin to GND for best transient response and stability.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlv74328pdbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`tlv74328pdbvr-etched.step`	2.1 MB	You want the part with `TLV74328PDBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 536 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.
