TMP709AIDBVR from UMW, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	SET	input	Temperature set point input. Connect an external 1% resistor between SET and GND to program the trip threshold. Input voltage range 0 to VCC; input leakage 1 µA max.
2	GND	power_in	Device ground reference.
3	OT	output	Open-drain, active-low overtemperature output. Asserts low when the measured temperature crosses the programmed threshold. Requires an external pull-up resistor; sinks 5 mA min / 12 mA typ at VOT = 0.3 V.
4	HYST	input	Hysteresis selection digital input. Tie HYST = VCC for 10°C hysteresis or HYST = GND for 2°C hysteresis. VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC.
5	VCC	power_in	Supply voltage input, 2.7 V to 5.5 V. Typical quiescent current 33 µA. Bypass with a 0.1 µF ceramic capacitor to GND.
