2A Sink/Source Bus Termination EUP7171 DESCRIPTION
... REFEN is an external reference input for the EUP7171. For SSTL-2 applications, VREF should be a 1.25V that the regulator can trace for termination voltage VOUT. It is recommended to place a 0.01uF to 0.1uF bypass capacitor at close to the VREF pin. An additional function included in the VREF is an a ...

Electrical ballast
An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
