This chip is a voltage regulator, not the audio amplifier. The part number i=
ndicates that it is a 5v fixed regulator.=20

They list multiple models of that chip. The one I think is closest is...
because of the variable output.  The amp does have level/volume pot on it. T=
he other datasheets in the list do not show a variable output.
