L78L08ABZ-TR from STMicroelectronics, in a TO-92-2.54mm. 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 | output | Regulated 8V positive output voltage, nominal 8V (7.68-8.32V at TJ=25°C) capable of supplying 0-100mA load current. |
| 2 | GND | power_in | Ground connection, common return for input and load currents. |
| 3 | VIN | power_in | Unregulated DC input voltage, operating range 10.5-23V with 1.7V typical dropout voltage above regulated output. |
