Lm317 Schaltung Poti. Lm317 adjustable regulator datasheet specifications. Ich hatte nur zwei 9 volt trafos deshalb habe ich sie nach dem gleichrichter zu 18 volt zusammengeschlossen.
Lm317 is an adjustable voltage regulator which takes an input voltage of 3 40v dc and provides a fixed output voltage of 1 25v to 37v dc. You need to connect the 240 ohm resistor between out and v adj then connect the pot between v adj and ground. Lm317 is a three terminal voltage regulator ic from national semiconductors.
The lm317 is an adjustable 3 terminal positive voltage regulator capable of supplying in excess of 1 5 a over an output voltage range of 1 2 v to 37 volts.
Input voltage can be up to 40v and output voltage can be adjusted from 1 2v to 37v. The shown value of 0r5 means that it won t current limit until about 2 5a 1r2 would give approx 1a. They are designed to supply more than 1 5 a of load current with an output voltage adjustable over a 1 2 to 37 v range. Ich hatte nur zwei 9 volt trafos deshalb habe ich sie nach dem gleichrichter zu 18 volt zusammengeschlossen.
