because your required voltage is so close to the supply voltage,
there isn't much in the line for a common regulator circuit to
maintain a stable regulated 9 volts

The data sheet for the L78D09CV 2 amp regulator gives the input voltage as
12 to 35.

However, the app is for a car, where the running voltage is more like 14.
