TMP36

Analog Devices · Temperature Sensor · SOT-23

The TMP36 is a low-voltage analog temperature sensor with a linear 10 mV/C output and a 500 mV offset so it can read below 0 C on a single supply. It needs no external calibration and reads temperature directly as a voltage, ideal for feeding an MCU ADC. This page shows the 3-lead SOT-23 (TMP36FT9).

Pinout

Pin Name Type Function
1 +VS power_in Positive supply voltage input, 2.7 V to 5.5 V (absolute max 7 V). Bypass to GND with a 0.1 µF capacitor close to the pin for stable readings.
2 VOUT output Analog temperature output. 10 mV/°C scale factor with 500 mV offset at 0°C (e.g. 750 mV at 25°C). Output range 100 mV to 2000 mV; drives 0 to 50 µA loads; short-circuit current limited to ~250 µA. Capable of driving 1 nF to 10 nF capacitive loads without oscillation.
3 GND power_in Device ground reference. Output voltage is measured with respect to this pin.
