LT3027EMSE#PBF from Analog Devices, in a MSOP-10-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	BYP2	passive	Channel 2 reference bypass pin, clamped internally to ±0.6V from ground, with a maximum 0.01µF capacitor recommended for 20µVRMS noise, and must be left unconnected if not used.
2	ADJ2	input	Channel 2 error amplifier input, internally clamped to ±7V, with a 30nA bias current flowing into the pin and regulating to 1.22V referenced to ground for an output range of 1.22V to 20V.
3	SHDN2	input	Channel 2 shutdown control, where the output turns off when pulled low, must be connected to VIN if unused, and draws a typical pin current of 1µA.
4	ADJ1	input	Channel 1 error amplifier input, internally clamped to ±7V, with a 30nA bias current flowing into the pin and regulating to 1.22V referenced to ground for an output range of 1.22V to 20V.
5	BYP1	passive	Channel 1 reference bypass pin, clamped internally to ±0.6V from ground, with a maximum 0.01µF capacitor recommended for 20µVRMS noise, and must be left unconnected if not used.
6	OUT1	power_out	Channel 1 regulated output, which requires a minimum 1µF output capacitor to prevent oscillations.
7	SHDN1	input	Channel 1 shutdown control, where the output turns off when pulled low, must be connected to VIN if unused, and draws a typical pin current of 1µA.
8	IN1	power_in	Channel 1 input supply operating from 1.8V to 20V, which withstands reverse voltages of 20V and benefits from a 1µF to 10µF bypass capacitor when far from the input filter.
9	IN2	power_in	Channel 2 input supply operating from 1.8V to 20V, which withstands reverse voltages of 20V and benefits from a 1µF to 10µF bypass capacitor when far from the input filter.
10	OUT2	power_out	Channel 2 regulated output, which requires a minimum 1µF output capacitor to prevent oscillations.
11	GND	power_in	Exposed pad ground that must be soldered to the PCB and electrically connected to ground.
