**MICRONE** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT23-3

ME6206A21M3G from MICRONE, in a SOT23-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VSS | power_in | Ground reference pin for the regulator (SOT23-3 pin 1 per the ME6206Axx/ME6206Kxx pin assignment table). |
