SL78L08 from Slkor(SLKORMICRO Elec.), 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 | VO | power_out | Regulated 8.0 V typical output (7.7 V to 8.3 V at Tj=25°C), rated for a maximum output current of 100 mA and tested with a 0.1 µF output capacitor. |
| 2 | GND | power_in | Common ground reference for the input and output, connected to the ground side of the 0.33 µF input and 0.1 µF output capacitors. |
| 3 | VI | power_in | Unregulated input; the absolute maximum is 30 V for the 3.3V-9V device group, the line-regulation test range is 10.5 V to 23 V, and dropout is 1.7 V typical. |
