AP62300WU-7 from Diodes Incorporated, in a TSOT-23-6. 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	VIN	power_in	Power Input. Supplies power to the IC as well as the step-down converter power MOSFETs. Drive VIN with a 4.2V to 18V source. Bypass VIN to GND with a suitably large capacitor (typ. 10µF) to eliminate switching noise.
2	SW	power_out	Power Switching Output. Switching node that supplies power to the output. Connect the output LC filter (inductor + output capacitor) from SW to the output load.
3	GND	power_in	Power Ground. Return path for both the input capacitor and the internal low-side power MOSFET.
4	BST	passive	High-Side Gate Drive Boost Input. Supplies the drive voltage for the high-side N-channel MOSFET. A 100nF or larger bootstrap capacitor is recommended from BST to SW.
5	EN	input	Enable Input. Digital input that turns the regulator on/off. Drive high to enable, low to disable. Leave floating for automatic startup. Precision 1.2V threshold allows use for programming the UVLO via a resistor divider.
6	FB	input	Feedback sensing terminal for the output voltage. Connect this pin to the resistive divider from VOUT to GND. Regulates to 0.800V (AP62300/AP62301) internal reference.
