A Darlington pair is a special arrangement of bipolar transistors that combines a high-gain transistor with a high-current transistor. The combined transistors allow both a higher gain and a larger amount of current to flow than would be possible with a single transistor. Darlington pairs are often used to drive motors. They can be bought packaged as a single discrete component or packaged as a transistor array, consisting of several transistors in a single integrated circuit (IC) (such as ULN2803 and ULN2003).&quot; [http://www.bbc.co.uk/schools/gcsebitesize/design/electronics/switchesrev3.shtml]<br /> <br /> http://www.bbc.co.uk/schools/gcsebitesize/design/images/sc_darlington_pair.gif</div>
