**MICRONE** · Linear Voltage Regulators (LDO) · SOT-23-5

ME6219C18M5G from MICRONE, in a SOT-23-5. 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 | Vin | power_in | Voltage input pin; the operating input voltage is 2.0V to 6.5V, and the absolute maximum Vin pin voltage is 6.5V. |
| 2 | Vss | power_in | Ground pin. |
| 3 | CE | input | Enable pin that turns the output on or off; the CE pin voltage must stay within Vss-0.3V to Vout+0.3V, and with CE at 0V the shutdown current is 0.1μA typ. (1μA max). |
| 4 | NC | unconnected | No connection. |
| 5 | Vout | power_out | Regulated voltage output, 1.2V to 5.0V in 0.1V steps with ±2% accuracy, rated up to 300mA output current. |
