MCP9700T-E from Microchip, 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	VDD	power_in	Positive supply pin. Operating range 2.3 V to 5.5 V (MCP9700/9700A). Absolute maximum 6.0 V. A 0.1 µF bypass capacitor to GND is recommended close to the pin.
2	VOUT	output	Analog temperature output. Rail-to-rail voltage proportional to sensed temperature with 10.0 mV/°C typical coefficient and 500 mV output at 0 °C. Output impedance ~20 Ω, drives up to 100 µA and 1000 pF cap loads; connect directly to an ADC input.
3	GND	power_in	Ground return for supply and output signal. 0 V reference for VOUT.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mcp9700t-e.step`	59 KB	You want the bare part, or you mark your own boards.
`mcp9700t-e-etched.step`	1.6 MB	You want the part with `MCP9700T-E` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 398 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.
