LT3063EMS8E-3.3#PBF from Analog Devices, in a MSOP-8-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	REF/BYP	passive	Reference/bypass pin: a single capacitor to GND bypasses reference noise (10nF gives about 30µVRMS, 10Hz to 100kHz) and sets soft-start time, is pulled low in shutdown, must be left floating if unused, and must not be driven by active circuitry.
2	ADJ	input	Error amplifier inverting input with 600mV reference voltage and typical 15nA bias current flowing out of the pin; sets the output voltage via a resistor divider.
3	OUT	power_out	Output pin supplying the load, requiring at least 3.3µF output capacitor, and actively discharged by an internal NMOS in shutdown (10µF discharged 90% in 2ms or less).
4	OUT	power_out	Output pin supplying the load, requiring at least 3.3µF output capacitor, and actively discharged by an internal NMOS in shutdown (10µF discharged 90% in 2ms or less).
5	IN	power_in	Input supply pin for 1.6V to 45V operation, needing a 1µF to 10µF bypass capacitor if far from the main filter capacitor, and withstands reverse voltage.
6	IN	power_in	Input supply pin for 1.6V to 45V operation, needing a 1µF to 10µF bypass capacitor if far from the main filter capacitor, and withstands reverse voltage.
7	SHDN	input	Shutdown input where pulling low turns the output off, which must be connected to IN if unused, cannot be driven below GND unless tied to IN, and has typical current below 3µA.
8	GND	power_in	Ground pin, tied directly to exposed pad Pin 9 and the PCB ground, with the output-setting resistor divider bottom connected directly to it.
9	GND	power_in	Exposed pad, ground, must be soldered to PCB and tied directly to Pin 8 and PCB ground for enhanced thermal performance.
