LM317 integrated regulator circuit

Published:2011/4/6 2:06:00 Author:Nicole | Keyword: integrated regulator | From:SeekIC

It is usual adjustment integrated regulator, the maximum output current is 2.2A, the output voltage is in the range of 1.25~37V. The connection is above. There is 1.25V voltage reference between 1, 2 pins. In order to ensure the output performance of regulator, R1 should lower than 240Ω. To change the resistance of R2 can adjust the regulator voltage value. D1, D2 is used to proect LM317.
