ADR441ARZ-REEL7 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	DNC	unconnected	Do Not Connect; do not connect to this pin.
2	VIN	power_in	Input voltage connection; operating range 3 V to 18 V for ADR441 (absolute maximum supply 20 V), with 0.1 µF capacitor required.
3	NIC	unconnected	Not Internally Connected; this pin is not connected internally.
4	GND	power_in	Ground.
5	TRIM	passive	Output voltage trim pin that adjusts the output over a ±0.5% range via a potentiometer between VOUT and GND.
6	VOUT	power_out	Output voltage (2.500 V for ADR441), sources up to 10 mA and sinks up to -5 mA, with 0.1 µF capacitor required.
7	NIC	unconnected	Not Internally Connected; this pin is not connected internally.
8	DNC	unconnected	Do Not Connect; do not connect to this pin.
