LT3090IMSE#PBF from Analog Devices, in a MSOP-12-EP. 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	IN	power_in	Input pin that supplies power to the regulator; all IN pins must be tied together and to the exposed pad, and an input bypass capacitor of 2.2µF to 4.7µF generally suffices.
2	IN	power_in	Input pin that supplies power to the regulator; all IN pins must be tied together and to the exposed pad, and an input bypass capacitor of 2.2µF to 4.7µF generally suffices.
3	IN	power_in	Input pin that supplies power to the regulator; all IN pins must be tied together and to the exposed pad, and an input bypass capacitor of 2.2µF to 4.7µF generally suffices.
4	ILIM	input	Current limit programming pin where an external resistor between ILIM and IN sets the limit with a nominal scale factor of 10A•kΩ, and ILIM must not be driven more than 0.3V below IN.
5	IMONP	output	Positive current monitor pin that sources current equal to 1/2000 of output current through a resistor to GND, and must be tied to IN for negative current monitoring.
6	IMONN	output	Negative current monitor pin that sinks current equal to 1/1000 of output current through a resistor to GND, and must be tied to GND if unused.
7	SHDN	input	Bidirectional shutdown pin where the output is off within ±0.45V of GND and turns on beyond ±1.4V, with maximum pin current of 7µA out or 30µA in, and it must not be floated.
8	SET	input	Inverting input of the error amplifier where a precision fixed 50µA current flows, and a resistor to GND sets the output voltage from zero to the -36V absolute maximum rating.
9	GND	power_in	Ground pin that supplies the quiescent current and the drive current to the NPN pass transistor, and must not be driven more than 0.3V below IN.
10	OUT	power_out	Output pin that supplies power to the load; all OUT pins must be tied together and a minimum 4.7µF output capacitor with ESR below 0.5Ω is required to prevent oscillations.
11	OUT	power_out	Output pin that supplies power to the load; all OUT pins must be tied together and a minimum 4.7µF output capacitor with ESR below 0.5Ω is required to prevent oscillations.
12	OUT	power_out	Output pin that supplies power to the load; all OUT pins must be tied together and a minimum 4.7µF output capacitor with ESR below 0.5Ω is required to prevent oscillations.
13	IN (EXPOSED PAD)	power_in	Exposed backside pad that is electrically connected to IN and the device substrate and must be soldered to the PCB for proper electrical and thermal performance.
