78L05A from Shikues, in a SOT-89. 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 output of the 78L05A, rated for a maximum output current of 200 mA with a nominal 5.0 V output (4.75 V to 5.25 V over the stated load range). |
| 2 | GND | power_in | Common ground and reference pin for the regulator; the datasheet gives no separate electrical limit for this pin. |
| 3 | IN | power_in | Unregulated input supply, with an absolute maximum input voltage of 30 V and a typical application using a 0.33 µF input capacitor C1 close to the regulator. |
