# LM35DT

**Texas Instruments** · Temperature Sensors · TO-220

LM35DT from Texas Instruments, in a TO-220. 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, recommended supply voltage 4 V to 30 V (absolute maximum 35 V). |
| 2 | GND | power_in | Device ground pin, connect to power supply negative terminal; the TO-220 tab is also connected to GND. |
| 3 | VOUT | output | Temperature sensor analog output, 10.0 mV/°C scale factor, able to drive 50 pF without special precautions. |

## CAD (KiCad official)

- Symbol: `LM35DT`
- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`
- 3D model: TO-220 (KiCad packages3D, STEP)
- 3D model files: `lm35dt-etched.step` / `lm35dt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm35dt.step` / `lm35dt.glb` are the bare package body.
