Which capacitors should I add around the regulator?
The L78L series datasheet practice is about 0.33 µF on the input and 0.1 µF on the output, placed close to the pins. Confirm the values in the manufacturer datasheet for your exact part.
What input voltage do I need?
The input must be higher than 9V by the regulator's dropout margin. Supplying a much higher voltage makes the regulator dissipate more heat, so keep the input only as high as needed.
