REF5025IDGKR from Texas Instruments, in a VSSOP-8-0.65mm. 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	DNC	unconnected	Do not connect. This pin must be left electrically unconnected on the PCB.
2	VIN	power_in	Input supply voltage. Recommended range is (V_OUT + 0.2V) to 18V for the REF50xxI/AI grade; absolute maximum 18V. Bypass with a 1µF ceramic capacitor to GND.
3	TEMP	output	Temperature monitoring pin. Provides a temperature-dependent output voltage (typ. 575mV at 25°C, sensitivity ~2.64mV/°C over -40°C to 125°C).
4	GND	power_in	Ground reference for the device.
5	TRIM/NR	passive	Output adjustment / noise reduction pin. Allows fine trim of V_OUT and/or connection of an external capacitor to reduce output noise. May be left floating if unused.
6	VOUT	output	Reference voltage output, nominally 2.500V for REF5025. Sources and sinks up to ±10mA. Requires a 1µF load capacitor for stability and turn-on settling.
7	NC	unconnected	No internal connection. May be left floating.
8	DNC	unconnected	Do not connect. This pin must be left electrically unconnected on the PCB.
