AP4306AUKTR-G1 from Diodes Incorporated, 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	VCTRL	input	Input pin of the voltage control loop, with transconductance gain Gmv of 2.5 to 3.5 mA/mV and input bias current of 50 nA typical at 25°C.
2	GND	power_in	Ground reference pin for the controller.
3	VOUT	output	Output pin that sinks current only, with low output voltage of 100 mV typical at 10 mA sinking current.
4	ICTRL	input	Input pin of the current control loop, with transconductance gain Gmi of 1.5 mA/mV minimum and input bias current of 18 µA typical at 25°C.
5	VSENSE	input	Input pin of the current control loop, with a current control loop reference of 70 mV typical (A version, 66.5 to 73.5 mV at 25°C).
6	VCC	power_in	Power supply pin, with recommended operating supply voltage of 2.5 V to 18 V and absolute maximum rating of 20 V.
