LM317LMX/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage for the LM317 is 40V, but it's recommended to keep it below 35V for reliable operation.

  • The output voltage of the LM317 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 = 1.25 * (1 + R2/R1).

  • The minimum input-to-output voltage differential required for the LM317 to regulate properly is around 2V. This is known as the 'dropout voltage'.

  • Yes, the LM317 can be used as a current source by adding a resistor in series with the output and adjusting the output voltage to regulate the current. However, this is not a recommended use case, and a dedicated current source IC would be a better choice.

  • To protect the LM317 from overheating, ensure good heat sinking, use a heat sink with a thermal resistance of less than 10°C/W, and keep the device within its recommended operating temperature range of 0°C to 125°C.
