LM317SX/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage for the LM317SX/NOPB is 40V, but it's recommended to keep it below 35V for reliable operation.
  • The output voltage of the LM317SX/NOPB can be adjusted by using a resistive divider network between the output and the adjust pin. The formula to calculate the output voltage is Vout = 1.25V * (1 + R2/R1) + Iadj * R2, where R1 and R2 are the resistors in the divider network and Iadj is the current flowing into the adjust pin.
  • The minimum input voltage required for the LM317SX/NOPB to regulate properly is 3V above the desired output voltage. For example, if you want an output voltage of 12V, the input voltage should be at least 15V.
  • The LM317SX/NOPB can handle up to 1.5A of output current, but it's recommended to keep it below 1A for reliable operation.
  • The dropout voltage of the LM317SX/NOPB is typically around 2V, which means that the input voltage should be at least 2V higher than the desired output voltage for proper regulation.
