UA78L09ACDR from Texas Instruments, in a SOIC-8. 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 | OUTPUT | output | Regulated output pin; place the recommended 0.1 µF output capacitor as close to the OUT and GND pins as possible. |
| 2 | COMMON | power_in | Ground pin (common/GND reference for the regulator). |
| 3 | COMMON | power_in | Ground pin (common/GND reference for the regulator). |
| 4 | NC | unconnected | No connect pin, not connected internally; connect to ground for best thermal performance or leave floating. |
| 5 | NC | unconnected | No connect pin, not connected internally; connect to ground for best thermal performance or leave floating. |
| 6 | COMMON | power_in | Ground pin (common/GND reference for the regulator). |
| 7 | COMMON | power_in | Ground pin (common/GND reference for the regulator). |
| 8 | INPUT | input | Unregulated input pin; use the recommended 0.33 µF input capacitor from the Recommended Operating Conditions table, placed as close to the IN and GND pins as possible. |
