LM20BIM7X from Texas Instruments, in a SC-70-5. 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	NC	unconnected	No connect. Must be left floating or grounded. Other signal traces must not be connected to this pin.
2	GND	power_in	Device substrate and die attach paddle; connect to power supply negative terminal. For optimum thermal conductivity to the PCB ground plane, pin 2 must be grounded. May also be left floating.
3	VO	output	Temperature sensor analog output. Output impedance ~160 Ω; transfer function VO = (-3.88e-6 × T²) + (-1.15e-2 × T) + 1.8639 V. Can source 16 µA and sink 1 µA maximum.
4	V+	power_in	Positive power supply pin. Operating range 2.4 V to 5.5 V; absolute maximum 6.5 V. Quiescent current typically 4.5 µA (10 µA maximum).
5	GND	power_in	Device ground pin; connect to power supply negative terminal.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lm20bim7x.step`	87 KB	You want the bare part, or you mark your own boards.
`lm20bim7x-etched.step`	1.5 MB	You want the part with `LM20BIM7X` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 391 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.
