Lm317 Ic Circuit Diagram. Lm317 pinout and basic circuit diagram. Output 100ma lm317k on to 3.
Using lm317 as a fixed voltage regulator with circuit lm317 as 7806 how to calculate the power dissipation in lm317 regulator when the heat sink should be used with lm317 ic protections for lm 317 circuit for different applications from lm317 datasheet. The most fundamental circuit that can be built using an lm317 ic is shown below. Internal short circuit current limiting or output is short circuit protected.
C1 is the input capacitance.
The lm317 ic has many features such as current limiting thermal protection and safe operating area protection. When the capacitance distance between the voltage regulator and the rectifier filter is less than 5 10cm c1 is not necessary. It can also be used as a precise current limiting device which is essential for testing electronic equipment. Typical positive voltage regulator circuit using lm317.
