LT3007ITS8#TRMPBF from Analog Devices, in a TSOT-23-8. 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	SHDN	input	Shutdown input: pulling low puts the device in a low power state and turns the output off; tie to VIN if unused, it cannot be left unconnected and cannot be driven below GND unless tied to IN.
2	GND	power_in	Ground; pins 2, 3 and 4 are normally tied to GND, and the bottom of the output resistor divider should connect directly to GND for best regulation.
3	GND	power_in	Ground; pins 2, 3 and 4 are normally tied to GND, and the bottom of the output resistor divider should connect directly to GND for best regulation.
4	GND	power_in	Ground; pins 2, 3 and 4 are normally tied to GND, and the bottom of the output resistor divider should connect directly to GND for best regulation.
5	IN	power_in	Input supply pin (operating range 2V to 45V); needs a 0.1µF to 10µF bypass capacitor if far from the main input filter capacitor, and withstands reverse voltages like a series blocking diode.
6	NC	unconnected	No connect, not tied to any internal circuitry; LTC recommends floating it for fault tolerant operation.
7	OUT	power_out	Regulated output supplying the load; requires a minimum output capacitor of 2.2µF to prevent oscillations.
8	ADJ	input	Error amplifier inverting input for the adjustable LT3007; regulated to 600mV referenced to GND (output range 0.6V to 44.5V), with 400pA typical bias current flowing out of the pin.
