5.333 Volt for Roland Filters

[Erik The ViKing]

Can anyone tell me this is a good idea for a 5.333 volt, as in Roland's
303-filter, power supply?????

A simple voltage divider connected to an opamp, followed by a voltage
follower. The voltage divider itself could exist of one resistor and a pot
to adjust the output-voltage for 5.333 volts.

Are there better ways of doing this???? And how critical is the 5.333 volt?
