Adjustable Voltage regulator using LM317

This paper explains about the importance of LM317 adjustable voltage Regulator. Now a days all the electronic devices are very sensitive. So, for proper operation of these equipments it is necessary to supply constant voltage to them. For maintain voltage as constant voltage regulator is required. We have mainly two types of voltage regulators. Those are fixed voltage regulators and variable voltage regulators. Variable voltage regulators are better than fixed voltage regulators. We have different types of variable voltage regulators among those LM317 is one of the best regulator it is very easy to carry and low cost. This article shows that the importance and variable applications of LM317 voltage regulator.
