A ballast resistor is a resistor inserted into a circuit to compensate for different changes. Others might give a different answer to the question “what is a ballast resistor” like this: A resistor ...
Designers use ballast ICs, such as International Rectifier’s IR53HD420, in CFLs (compact fluorescent lamps) for heating the filaments, igniting the lamps, and supplying the lamps with current ...
The data sheet for the LT3080 linear voltage regulator suggests using printed-circuit-board (PCB) traces for ballast resistors. Although the LT3080’s low offset voltage suits it well for this ...
