TLV803SDBZR from Texas Instruments, in a SOT-23. 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	GND	power_in	Ground reference pin (0 V). All voltages are referenced to this pin.
2	RESET	output	Active-low open-drain RESET output. Driven low when VDD falls below the negative-going threshold VIT- (2.93 V for TLV803S) and remains low for the delay time td (200 ms typ) after VDD exceeds VIT-. Requires a 10 kΩ to 1 MΩ external pull-up; pull-up voltage is not limited to VDD.
3	VDD	power_in	Supply voltage input. Recommended operating range 1.1 V to 6 V; absolute maximum 7 V. Place a 0.1 µF ceramic bypass capacitor close to this pin. Supply current IDD ≈ 9 µA typ.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlv803sdbzr.step`	59 KB	You want the bare part, or you mark your own boards.
`tlv803sdbzr-etched.step`	2.1 MB	You want the part with `TLV803SDBZR` 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 69 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.
