Darlington Pair. Here the darlington pair provides significant levels of current gain a feature that is important in linear regulators. Darlington pair allows users to drive more power applications by few milliamp of current source from micro controller or low current sources.
A darlington transistor also known as a darlington pair is an electronics component made via the combination of two bjts bipolar junction transistor connected in such a way that it allows a very high amount of current gain. The pair of bipolar transistors provides a very high current gain as compared with single standard transistor as mentioned above. Is a name given to a cascaded set of transistors both being of the same type say npn or pnp.
Darlington pair circuit in linear power regulator the darlington pair circuit finds many applications as the series pass element in a linear regulator.
Although the darlington pair has some limitations it is nevertheless used in many areas especially where high frequency response in not needed. Cc by sa 3 0 by wikipedia user michael9422 a common darlington pair is the tip120 which is a great choice for the examples later in this guide. This mean that a tiny amount of current from a sensor micro controller or similar can be used to drive a larger load.
