LM317 integrated voltage regulator circuit

Published:2011/8/29 3:36:00 Author:TaoXi | Keyword: integrated voltage, regulator circuit | From:SeekIC

The LM317 is designed as the common adjustable integrated voltage regulator with the maximum output current of 2.2A, the output voltage range is 1.25-37V. The connection method is: The reference voltage between pin-1 and pin-2 is 1.25V. In order to ensure the output voltage stabilizer performance, R1 is smaller than 240ohms. You can adjust the voltage regulator value by adjusting the value of R2. The D1 and D2 can be used to protect the LM317. Uo=(1+R2/R1)*1.25 The LM317 integrated voltage regulator circuit
