ME6228A50PG from MICRONE, in a SOT-89-3. 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 reference (地). Common return for input and output currents; connect directly to the system ground plane. |
| 2 | VIN | power_in | Power supply input (电源输入端). Accepts 5.0V to 30V (absolute max 30V). Recommended input capacitor CIN = 10µF; when VIN > 15V an electrolytic or tantalum input cap is required due to ceramic-cap inrush spiking. |
| 3 | VOUT | power_out | Regulated voltage output (电压输出端). Fixed 5.0V ±2% for the A50 option; delivers up to 150mA (typ) with 18mA typical short-circuit current limit. Requires low-ESR ceramic output capacitor (COUT = 20µF recommended). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 452 faces against 42 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.
