**MICRONE** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT23-3

ME6228A30M3G from MICRONE, in a SOT23-3. 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 reference pin (地) for the regulator; the datasheet gives no separate electrical limit for this pin. |
| 2 | VOUT | power_out | Regulated voltage output; for the ME6228A30 the specified output is 3.0 V ±2% with a maximum output current of 150 mA, and the absolute maximum rating is VSS−0.3 V to VIN+0.3 V. |
| 3 | VIN | power_in | Supply input; for the ME6228A30 VIN must be 3.0 V to 30 V (absolute maximum 30 V), and an electrolytic or tantalum input capacitor is required when VIN exceeds 15 V. |
