- Published on 26 Oct 15

a. Series-Switching Regulator
b. Series Dissipative Regulator
c. Special Regulators
d. None of the above

ANSWER: Series Dissipative Regulator
 
LM317 is an adjustable & series dissipative regulator as they exhibit simulation of variable resistance between input and load. However, the mode of functionality is approved to be linear. These linear regulator are specifically designed to control or regulate constant output voltage by dissipation of excessive power in the form of heat when the input voltage and load current shows variations for certain extent. However, LM317 are considered as 'Series Dissipative Regulators'. The conversion efficiency in series dissipative regulator is inversely proportional to input/output differential value.
Thus, they are applicable to medium current applications where it becomes possible to manage dissipated power with heat sinks.
