LM45BIM3X 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 supply voltage input; operating range +4.0 V to +10 V, typical quiescent current 120 μA (max 160 μA) over the full supply range. |
| 2 | OUTPUT | output | Analog voltage output linearly proportional to temperature at +10.0 mV/°C (9.7 mV/°C min, 10.3 mV/°C max); output impedance 20 Ω at 1 mA load; rated over −20°C to +100°C. |
| 3 | GND | power_in | Ground return; die backside is directly attached to this pin to ensure good thermal conductivity to the board. |
