Quiescent current into the TDA2822 is around 6ma, peaks can be 1 Amp.
Though?100ma might be sufficient for moderate speaker volumes.
You would need two resistors for a voltage divider, and maybe waste 500 ma through them
to keep the voltage moderately well regulated.
Good spot for an LM7805.

One could use a voltage drop resistor. The higher the current draw, lower would be the voltage to the TDA2822
