Texas Instruments · Temperature Sensors · SC-70-5

LMT87DCKR from Texas Instruments, in a SC-70-5. 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	VDD	power_in	Positive supply voltage. Operating range 2.7 V to 5.5 V (absolute max 6 V). Quiescent current is typically 5.4 μA. Bypass with a ceramic capacitor near the pin.
2	GND	power_in	Power supply ground. This pin has a direct connection to the back side of the die, so it should be tied to the system ground/thermal reference.
3	OUT	output	Analog output. Outputs a voltage that is inversely proportional to temperature with an average slope of -13.6 mV/°C. Class-AB push-pull output can source/sink up to ±50 μA and is short-circuit protected. Output voltage range approximately 0.2 V to 3.3 V over the -50°C to 150°C temperature range.
4	VDD	power_in	Positive supply voltage (internally connected to pin 1 and pin 5). Tie to VDD or leave to be handled by the pin 1 connection.
5	VDD	power_in	Positive supply voltage (internally connected to pin 1 and pin 4). Tie to VDD or leave to be handled by the pin 1 connection.
