Lm317 adjustable voltage regulator circuit diagram.

Lm317 variable voltage regulator circuit lm117 lm217 lm317 variable voltage regulator characteristics. The lm317 ic helps in current limiting thermal overload protection and safe operating area protection. Input voltage is fed to the pin3 v in of the ic and regulated output voltage is available from pin 2 v out of the ic. In most of the applications due to irregular loads the output voltage produced has fluctuations in it which can lead to damaging loads.

Adjust voltage in steps 3v 6v 9v 12v. Circuit diagram lm317 voltage regulator ic it s an adjustable three terminal voltage regulator ic with a high output current value of 1 5a. In input out output adj adjust. Resistor network comprising of r1 and r2 connected in association to the pin1 adj is used to set the output voltage.

It can supply greater than 1 5 a at the output. Lm317 adjustable regulator a classic voltage regulator circuit using lm317 is shown above. Lm317 is a positive voltage regulator with an adjustable voltage range from 1 25 v to 37 v. With automatic charging and full charged indicator using tl431.

The lm317 circuit is shown in the below figure is a t y pical configuration of the lm317 voltage regulator circuit diagram including the decoupling capacitors. The lm317 is a 3 terminal positive voltage regulator with a 1 25 to 37 volts output voltage range. This lm317 circuit is capable to provide variable dc power supply with an output of 1a and can be adjusted up to 30v. And in fine 1 25v to 20v.

The three terminals are input pin output pin and adjustment pin.
