Cards in this set: Term A circuit that prevents further damage to the external circuit and prevents damage to the power supply is known as a _________ __________. Definition Current Limiter Term A _________ _________ is a signal device that uses two transistors. Definition Darlington Pair Term In a darlington pair, the difference in voltage between the base and emitter is ________? Definition 1.2 VDC Term The final collector current through a darlington pair is equal to a factor of _____ squared. Definition Beta Term When ______ occurs, regulation is lost because it is impossible to hold both voltage and current constant under changing load conditions. Definition Fold-Back Term Any single transistor or darlington pair that is connected in series to the load so all the current must go through it is known as a _________. Definition Pass Transistor Term As the emitter to base voltage of the darlington pair decreases, the current will essentially remain ________? Definition Constant Term A darlington pair configuration is ________ connected? Definition Externally Term When the darlington pair saturates, the voltage between the collector and the emitter can never go below _______? Definition One diode drop (600mV) Term Darlington pairs can be thought of as a _______ ________. Definition Super Transistor Term In a darlington pair, there is _____ collector, ______ bases, and ______ emitters. Definition One, One, One! Term A ________ _______ circuit is an essential element of a power supply. Definition Current Limiting Term The main difference between a current regulator and a voltage regulator is that a _______ has been added in series with the transistor to detect current changes. Definition Resistor Term A decrease in load voltage that accompanies limiting is called ______. Definition Fold-Back
