ZXSC380FHTA from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VCC	power_in	Supply voltage input. Generally connected to a single Alkaline, NiMH or NiCd cell. Operating range 0.8V to 6V; absolute max 10V. Start-up voltage 0.9V typical (1.0V max).
2	VOUT	output	Switch output to external inductor / LED. Open-collector switching node from the internal transistor; connect the boost inductor between VCC and this pin, with LED to VOUT. Absolute max 20V, output switch current 200mA.
3	GND	power_in	Ground reference for the device.
