Lm317 Pinout Diagram. Internal short circuit current limiting or output is short circuit protected. If you grab lm317 upside down while ic s printed name is facing towards you and it s pins are on top then the left pin is the input pin the center pin is output pin while the right pin is the adjustment pin.
Output adjustable between 1 2v and 37v. Now before working with the lm317 voltage regulator we should know the pros corns of the lm317. The nominal output voltage is selected by means of a resistive divider.
Explained lm317 variable voltage regulator pinout main features uses and connection diagram.
Looking from the front of the voltage regulator the first pin on the left is the adjustable pin the middle is vout and the last pin on the right is v in. It has many application circuits in its datasheet but this ic is known for being used as a variable voltage regulator. Looking from the front of the voltage regulator the first pin on the left is the adjustable pin the middle is vout and the last pin on the right is v in. Lm317 pinout lm317 has 3 pins and a transistor like to 220 shape which makes it easier to fit on heatsinks.
