AL8807AW5-7 from Diodes Incorporated, in a SOT-25. 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	SW	output	Switch pin - drain of the internal high-side MOSFET. Connect the inductor and freewheeling diode here; keep this trace short to minimize EMI. RDS(on) typ 0.25 Ω (SOT25); absolute max SW voltage -0.3 to +40 V; peak switch current 2.5 A.
2	GND	power_in	Ground return pin. Dominant conduction path for the SOT25 package (also the thermal reference for ΨJL = 50 °C/W).
3	CTRL	input	LED current analog dimming control input (no PWM function). Internally tied to a 2.5 V VREF via a 50 kΩ resistor: floating gives nominal IOUT = 0.1/RS. 0.25 V < VCTRL < 2.5 V linearly adjusts output from 10% to 100% of IOUTnom. Absolute max -0.3 to +6.0 V. A capacitor here also implements soft-start.
4	SET	input	Set-nominal-output-current pin. An external resistor from VIN to SET sets the peak/average LED current (IOUTnom = 0.1/RS). Typical ISET = 16 µA when VSET = VIN − 0.1 V.
5	VIN	power_in	Input supply pin, 6 V to 36 V operating (absolute max 40 V). Must be locally decoupled to GND with ≥ 2.2 µF X7R ceramic capacitor.
