Lm317 adjustable voltage regulator circuit diagram.

Lm317 variable voltage regulator circuit lm117 lm217 lm317 variable voltage regulator characteristics. Lm317 adjustable regulator a classic voltage regulator circuit using lm317 is shown above. Adjust voltage in steps 3v 6v 9v 12v. Using lm317 and 2n3055 so easy and cheap.

This lm317 circuit is capable to provide variable dc power supply with an output of 1a and can be adjusted up to 30v. In input out output adj adjust. Lm317 is a positive voltage regulator with an adjustable voltage range from 1 25 v to 37 v. 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 circuit is shown in the below figure is a t y pical configuration of the lm317 voltage regulator circuit diagram including the decoupling capacitors. 4 lead acid battery charger circuits see 4 lm317 lead acid battery charger circuits for 6v 12v and 24v battery. 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. Resistor network comprising of r1 and r2 connected in association to the pin1 adj is used to set the output voltage.

With automatic charging and full charged indicator using tl431. The three terminals are input pin output pin and adjustment pin. It can supply greater than 1 5 a at the output. The lm317 ic helps in current limiting thermal overload protection and safe operating area protection.

The lm317 is a 3 terminal positive voltage regulator with a 1 25 to 37 volts output voltage range.
