# LMT90DBZT

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

LMT90DBZT 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 with supply voltage range 4.5V to 10V. |
| 2 | VO | output | Temperature sensor analog output; transfer function VO = (10mV/°C × T°C) + 500mV. |
| 3 | GND | power_in | Device ground pin, connected to negative power supply terminal. |

## CAD (KiCad official)

- Symbol: `LMT90DBZT`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `lmt90dbzt-etched.step` / `lmt90dbzt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lmt90dbzt.step` / `lmt90dbzt.glb` are the bare package body.
