# LM61BIM3

**Texas Instruments** · Temperature Sensors · SOT-23

LM61BIM3 from Texas Instruments, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | +VS | power_in | Positive power supply pin, operated within the recommended supply range of 2 V to 10 V. |
| 2 | VOUT | output | Temperature sensor analog output, 10 mV/°C with a 600 mV offset, with output current limited to 10 mA absolute maximum. |
| 3 | GND | power_in | Device ground pin connected to the power supply negative terminal; the die backside is attached to this pin for thermal conduction. |

## CAD (KiCad official)

- Symbol: `LM61BIM3`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `lm61bim3-etched.step` / `lm61bim3-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm61bim3.step` / `lm61bim3.glb` are the bare package body.
