HE6206-28NR from HEERMICR, 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 (VSS). Common reference for the internal bandgap reference, error amplifier, and pass transistor. Tie directly to the system ground plane close to CIN and CL.
2	VOUT	power_out	Regulated LDO output. Nominal 2.8V (±2%) for the HE6206-28 option, source current up to 300 mA (limited by Pd = 0.20 W in SOT-23 → IOUT = Pd/(VIN−VOUT)). Requires a ~1.0 uF ceramic load capacitor (CL) to ground for stability.
3	VIN	power_in	Unregulated input supply. Operating range up to 8V absolute maximum; must be at least VOUT + dropout (typ. 0.19V @ Iout=100mA for Vout≥2.8V). Decouple with a ~1.0 uF ceramic input capacitor (CIN) to VSS.
