ME6214A33M3G from MICRONE, 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 | VSS | power_in | Ground reference pin (接地引脚). Connect to system ground; carries return current for both quiescent bias (~0.7 uA) and load current (up to 300 mA). |
| 2 | VOUT | power_out | Regulated voltage output (电压输出端). Fixed 3.3 V ±2% for the A33 option, delivers up to 300 mA with 160 mV typical dropout at 100 mA. Requires a 1 uF output capacitor (CL) to VSS for stability. |
| 3 | VIN | power_in | Unregulated supply input (电压输入端). Operating range 2.0 V to 18 V; absolute maximum 18 V. Requires a 1 uF input capacitor (CIN) to VSS for stability. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 540 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
