MAX6325CSA+ from Maxim Integrated, in a SOP-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	I.C.	unconnected	Internally connected pin; the datasheet says do not use it.
2	IN	power_in	Positive power-supply input with an input voltage range of 8V to 36V.
3	NR	passive	Optional noise-reduction capacitor connection for wideband noise reduction (1µF shown in Figure 2); leave open if not used.
4	GND	power_in	Ground reference for the device.
5	TRIM	input	External trim input allowing ±1% output adjustment (Figure 1); leave open if not used.
6	OUT	power_out	Voltage reference output, specified for sourcing 0mA to 15mA and sinking -15mA to 0mA.
7	I.C.	unconnected	Internally connected pin; the datasheet says do not use it.
8	I.C.	unconnected	Internally connected pin; the datasheet says do not use it.
