LM3880MFE-1AB from Texas Instruments, in a SOT-23-6. 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	VCC	power_in	Input supply pin, with a recommended range of 2.7 V to 5.5 V to GND and an absolute maximum of 6 V.
2	GND	power_in	Ground reference pin for the device.
3	EN	input	Precision enable input whose recommended voltage range is -0.3 V to VCC + 0.3 V.
4	FLAG3	output	Open-drain output flag 3, which may be pulled up to a separate supply no more than 0.3 V above VDD, with a maximum flag ON current of 50 mA.
5	FLAG2	output	Open-drain output flag 2, which may be pulled up to a separate supply no more than 0.3 V above VDD, with a maximum flag ON current of 50 mA.
6	FLAG1	output	Open-drain output flag 1, which may be pulled up to a separate supply no more than 0.3 V above VDD, with a maximum flag ON current of 50 mA.
