L78L05ACUTR-CN from ChipNobo, in a SOT-89-3L. 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 | OUT | power_out | Regulated 5V output (typical 5.00V, 4.80-5.20V at 25℃), delivering up to 0.1A maximum output current, with a recommended 0.1uF output bypass capacitor placed close to the regulator. |
| 2 | GND | power_in | Ground reference for the regulator, common to input and output capacitors. |
| 3 | IN | power_in | Unregulated input voltage with absolute maximum 30V, with a recommended 0.33uF input bypass capacitor placed close to the regulator. |
