ME6118A12B3G from MICRONE, in a SOT-223. 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 | GND | power_in | Ground pin; the datasheet defines the regulated output as the voltage between the output and ground pins. |
| 2 | VOUT | power_out | Regulated output for the 1.2 V ME6118A12 with ±2% accuracy, specified up to 800 mA maximum output current, with the output voltage limited to Vss-0.3 V to VIN+0.3 V. |
| 3 | VIN | power_in | Power input with an operating range of 2.5 V to 18 V and an absolute maximum input voltage of 18 V; the A12 electrical specifications assume VIN = VOUT + 1.3 V. |
