CBM810SST3 from Corebai Microelectronics, in a SOT23-3. 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. All signals are referenced to this 0 V node.
2	RESET	output	Active-HIGH push-pull reset output for the CBM810X family. Asserts HIGH when VCC falls below the reset threshold (VRST = 2.93 V typ for 'S' option) and remains HIGH for 240 ms (typ) after VCC recovers above VRST. VOH = 0.8*VCC min at ISOURCE = 150 µA down to VCC = 1.8 V.
3	VCC	power_in	Monitored supply voltage input, 1.0 V to 5.5 V operating range. Absolute max -0.3 V to +6 V. Typical quiescent current 17 µA (VCC < 3.6 V). Reset threshold compared against this rail.
