# LM34DZ

**Texas Instruments** · Temperature Sensors · TO-92

LM34DZ from Texas Instruments, in a TO-92. 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; supply voltage range is 4 V to 30 V (recommended operating conditions). |
| 2 | VOUT | output | Temperature sensor analog output, 10 mV/°F linear scale factor, can source current but sink only about 1 µA. |
| 3 | GND | power_in | Device ground pin, connect to power supply negative terminal. |

## CAD (KiCad official)

- Symbol: `LM34DZ`
- Footprint: `Package_TO_SOT_THT:TO-92_Inline`
- 3D model: TO-92 (KiCad packages3D, STEP)
- 3D model files: `lm34dz-etched.step` / `lm34dz-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm34dz.step` / `lm34dz.glb` are the bare package body.
