ME6231A33M3G 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 / negative supply return for the regulator. Connect directly to the system ground plane; the input and output decoupling capacitor return currents should share this node with a low-impedance path. |
| 2 | VOUT | power_out | Regulated 3.3 V output pin. Sources up to 500 mA (typ) with ±1% accuracy; requires a ≥1 µF (10 µF recommended, X5R/X7R ceramic) output capacitor for stability and transient response. Internally clamped by active-discharge FET when the regulator is disabled. |
| 3 | VIN | power_in | Unregulated input supply, 3 V to 18 V operating range (20 V absolute max). Decouple to VSS with a ≥1 µF (10 µF recommended) X5R/X7R ceramic capacitor placed close to the pin. VOUT + 1 V minimum headroom is needed to stay out of dropout at rated load. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 569 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.
