The output falls about 5.5 mV per degree C over a -50 to 150 C range, sitting near mid-supply at room temperature, and the low 5.4 uA supply current suits battery designs. Its low output impedance drives an ADC input or a comparator without a buffer. A small, cheap analog thermometer, the SC70 sibling to the classic LM35.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GND | power_in | Power supply ground. On the SOT/SC70 (DCK) package pin 1 is a direct connection to the back side of the die and must be tied to GND. |+| 2 | GND | power_in | Power supply ground. On the SOT/SC70 (DCK) package pin 2 is also a direct connection to the back side of the die and must be tied to GND. |+| 3 | OUT | output | Analog output. Outputs a voltage that is inversely proportional to temperature with an average sensor gain of -5.5 mV/°C. Push-pull output with ±50 µA drive capability; short-circuit protected. |+| 4 | VDD | power_in | Positive supply voltage, 1.5 V to 5.5 V. Quiescent current is 5.4 µA typical. Bypass to GND with a small ceramic capacitor close to the pin. |+| 5 | GND | power_in | Power supply ground. Tie to the system ground plane. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Analog temperature sensor (voltage output) |+| Range | -50 to 150 C |+| Output slope | -5.5 mV/C |+| Accuracy | +/-0.4 C (typ) |+| Supply current | 5.4 uA (typ) |+| Supply | 1.5-5.5 V |+| Package | SC70-5 |++## Ordering variants++- `LMT84DCKR (SC70-5)`+- `LMT84LP (TO-92)`+- `LMT84LPG (TO-92, bulk)`++## CAD (KiCad official)++- Symbol: `Sensor_Temperature:LMT84DCK (KiCad official)`+- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`+- 3D model: SC70-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/lmt84.pdf) (30 pp, sha256 `ad87d637ced4b846`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
