AL5816W5-7 from Diodes Incorporated, 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	PWM	input	PWM dimming input for the LED, supporting dimming frequencies higher than 200Hz. Internal ~15µA pull-up to VCC; falling threshold ~2.5V (min 2.37V, max 2.63V). VIH ≥ 2.7V, VIL ≤ 2.3V. Absolute max range -0.3V to VCC.
2	GND	power_in	Device ground reference for supply, feedback, and control signals.
3	FB	input	Feedback input regulated to a nominal 200mV (192-208mV). LED current is set by a sense resistor between this pin and GND (I_LED = 0.2V / R_S). FB input bias current is typically -125nA. Absolute max range -0.3V to +6V.
4	OUT	output	Driving output to an external bipolar transistor base or MOSFET gate. Sources up to 15mA (typ) at VOUT ≤ 1V; sink capability ≥ 1mA. Output voltage swing 0V to ~4V. Absolute max range -0.3V to +6V.
5	VCC	power_in	Input supply. Operating range 4.5V to 60V (absolute max 65V). Typical supply current ~10.25mA at VOUT = 10mA load; UVLO rising ~4.2V, falling ~3.85V. Bypass with 0.1µF and 10µF capacitors to GND.
