ME6249A33PG from MICRONE, in a SOT-89-3. 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 pin (地) for the regulator; the datasheet gives no separate electrical limit for this pin. |
| 2 | VIN | power_in | Power supply input (电源输入端); for the ME6249A33 the input voltage is specified at 3.3 V to 18 V, with an absolute maximum of 20 V. |
| 3 | VOUT | power_out | Regulated voltage output (电压输出端); the ME6249A33 nominal output is 3.3 V with ±1% accuracy and up to 250 mA maximum output current. |
