BL8536CB3TR36 from BL Shanghai Belling, in a SOT-23. 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	GND	power_in	Ground reference for the converter. Return path for input and output ceramic capacitors; keep trace as short as possible to the output cap ground.
2	SW	power_out	Switching node. Connects the internal synchronous power stage to the external boost inductor (typ. 2.2uH-4.7uH) which ties back to VIN. Absolute maximum -0.3V to 6V.
3	OUT	power_out	Regulated boost output voltage pin (3.6V for CB3TR36 variant, factory-set range 1.8V-3.6V). Also supplies the IC's internal bias once started. Requires a 10uF low-ESR ceramic capacitor closely connected to GND; absolute maximum -0.3V to 6V.
