Low-Voltage Regulator Considerations
When installing a Music Rail
after a low-voltage regulator (as in a DAC or other digital application), you
may wish to consider the insertion loss (dropout) of the Music Rail.
A typical DAC chip is fed from a +5V regulator and a +3.3V regulator. Note that the 2A Music Rail drops 0.5V. This dropout or insertion loss can be compensated by the technique detailed in this application.
