EG78L05 from EG Micro, in a SOT-89-3. 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 | VOUT | power_out | Regulated 5V output, supplying up to 100mA maximum output current with 4.82V to 5.18V output at Tj=25°C. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | VIN | power_in | Unregulated input voltage; absolute maximum input is 30V minimum rating for 3.3V to 10V output versions, and 7V to 20V is the specified operating input range for the 5V output. |
