MCP9701AT-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 input. Operating range 3.1 V to 5.5 V for MCP9701/9701A. Absolute maximum 6.0 V. Bypass locally with ~0.1 uF to GND.
2	VOUT	output	Analog temperature output. Linear transfer function V_OUT = Tc*Ta + V0degC, with Tc = 19.5 mV/degC (typ) and V0degC = 400 mV (typ). Output impedance ~20 ohm; drives loads up to 1000 pF (typ) and up to 100 uA. Connect directly to an ADC input.
3	GND	power_in	Ground / negative supply reference for the sensor and its analog output.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mcp9701at-e.step`	59 KB	You want the bare part, or you mark your own boards.
`mcp9701at-e-etched.step`	1.5 MB	You want the part with `MCP9701AT-E` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 393 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.
