HX6206P212MR from HX hengjiaxing, 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	VSS	power_in	Ground / negative supply return (芯片接地端). Common reference for VIN and VOUT.
2	VOUT	power_out	Regulated output (芯片输出端). Nominal 2.1 V for the P212 option, ±2.5 % initial accuracy. Requires a ≥1 μF (typ.) output capacitor to Vss for stability. Delivers up to 250 mA (Vin=4.3 V, Vout=3.3 V); short-circuit current ≈30 mA, over-current limit ≈380 mA.
3	VIN	power_in	Unregulated input supply (启动输入端). Operating range 1.8 V - 8.0 V (absolute max 6.5 V per abs-max table); dropout ~200 mV @ 50 mA for a 2.1 V variant. Requires a ≥1 μF (typ.) input capacitor to Vss.
