LM61CIM3X 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 | +VS | power_in | Positive power supply pin. Operating range 2.7 V to 10 V (absolute max 12 V). Typical quiescent current 82 µA (125 µA max). |
| 2 | VO | output | Temperature sensor analog output. VO = (10 mV/°C × T°C) + 600 mV. Output impedance ≈800 Ω; drive to ground through no less than internal spec, output current max 10 mA. |
| 3 | GND | power_in | Device ground pin, connected to power supply negative terminal. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 362 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.
