ADR425BRZ from Analog Devices, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	TP	unconnected	Test pin reserved for factory testing; there are actual connections in TP pins, and users should not connect anything to it, otherwise the device may not function properly.
2	VIN	power_in	Input voltage; the ADR425 operating range is 7 V to 18 V, and the absolute maximum supply voltage is 18 V.
3	NIC	unconnected	No internal connection; the pin has no internal connections.
4	GND	power_in	Ground pin, defined as 0 V.
5	TRIM	passive	Trim terminal that adjusts the output voltage over a ±0.5% range without affecting the temperature coefficient; the datasheet recommends low temperature coefficient trim potentiometer and resistors, preferably <100 ppm/°C.
6	VOUT	power_out	Output voltage, 5.00 V nominal for the ADR425, with guaranteed load current up to 10 mA.
7	NIC	unconnected	No internal connection; the pin has no internal connections.
8	TP	unconnected	Test pin reserved for factory testing; there are actual connections in TP pins, and users should not connect anything to it, otherwise the device may not function properly.
