Lm317 Adjustable Voltage Regulator Circuit Diagram

High quality 3a adjustable voltage regulator.

Lm317 adjustable voltage regulator circuit diagram.

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. Using lm317 and 2n3055 so easy and cheap. The three terminals are input pin output pin and adjustment pin. With automatic charging and full charged indicator using tl431.

And in fine 1 25v to 20v. Adjust voltage in steps 3v 6v 9v 12v. The lm317 ic helps in current limiting thermal overload protection and safe operating area protection. In most of the applications due to irregular loads the output voltage produced has fluctuations in it which can lead to damaging loads.

The lm317 regulator terminals are. This lm317 circuit is capable to provide variable dc power supply with an output of 1a and can be adjusted up to 30v. Lm317 variable voltage regulator circuit lm117 lm217 lm317 variable voltage regulator characteristics. The lm317 is a 3 terminal positive voltage regulator with a 1 25 to 37 volts output voltage range.

It can supply greater than 1 5 a at the output. 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. 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.
