HX809TDBZRG from HANSCHIP semiconductor, in a SOT-23-3. 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 for the device (0 V). All supply and output voltages are referenced to this pin.
2	RESET	output	Active-low reset output. Asserted low when VCC drops below the reset threshold Vth (typ. 3.08 V for the T variant) and held low for the ~200 ms reset delay (Trp) after VCC returns above threshold. Drive capability: VOL <= 0.3 V @ ISINK = 1.2 mA; VOH >= 0.8*VCC @ ISOURCE = 500 uA.
3	VCC	power_in	Supply and monitored input voltage. Operating range 1.0 V to 6.0 V; absolute max 6.5 V. Typical quiescent current 5.5 uA at VCC = 6 V, no load. The internal comparator monitors this pin against the fixed threshold Vth.
