# ME6228A50M3G

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

ME6228A50M3G 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) of the regulator; the datasheet gives no electrical limit for this pin. |
| 2 | VOUT | power_out | Regulated voltage output; the absolute maximum output voltage range is VSS-0.3 V to VIN+0.3 V, and the maximum output current is 150 mA (nominal 5.0 V ±1% for the ME6228A50). |
| 3 | VIN | power_in | Power supply input; the ME6228A50 operating input range is 5.0 V to 30 V (absolute maximum 30 V), and a tantalum or electrolytic input capacitor is recommended when VIN exceeds 15 V. |
