ME6239A33M3G from MICRONE, 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 reference for the LDO. Connect to system ground. |
| 2 | VOUT | power_out | Regulated voltage output. Fixed 3.3V for the A33 option (accuracy ±1%). Capable of sourcing up to 250mA when VIN >= VOUT+1.5V. Bypass with a low-ESR ceramic capacitor (10uF X5R/X7R typical); use 20~100uF to suppress overshoot on fast VIN transients. |
| 3 | VIN | power_in | Unregulated supply input. Operating range up to 30V absolute maximum. Bypass with a 10uF ceramic capacitor; use an electrolytic or tantalum input cap when VIN > 15V to absorb hot-plug/turn-on spikes that could otherwise exceed 40V and damage the device. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 598 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.
