APS2410ES5-ADJ from Wuxi Chipown Micro electronics, in a SOT-23-5. 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	RUN	input	Regulator enable control input. Drive above 1.5V to turn the part on; drive below 0.6V to shut it down (<1uA supply current). Must not be left floating.
2	GND	power_in	Device ground return. Connect the (-) plate of the input decoupling capacitor closely to this pin.
3	SW	output	Power switch node output. Connects to the drains of the internal P-CH and N-CH MOSFETs; drives the external inductor. Peak current up to 1.4A.
4	VIN	power_in	Supply input pin, 2.5V to 6.5V (abs max +7V). Must be decoupled to GND with a 2.2uF (typ. 4.7uF) or greater X5R/X7R ceramic capacitor placed as close as possible.
5	VFB	input	Feedback input pin for the adjustable (-ADJ) version. Connect to the center point of the external resistor divider from VOUT to GND; internal reference threshold is 0.6V (VOUT = 0.6V x (1 + R2/R1)).
