ME6231C18M5G 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, operating range 3V to 18V (absolute maximum -0.3V to 20V). |
| 2 | Vss | power_in | Ground pin. |
| 3 | CE | input | Active-high chip enable (high level at least 1.7V turns on, low level at most 0.5V turns off); must not be left floating. |
| 4 | NC | unconnected | No connection (empty pin). |
| 5 | VOUT | power_out | Regulated voltage output (1.8V for ME6231C18), with maximum output current of 500mA. |
