LM317AMDTX/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 LM317 is rated for a maximum output current of 1.5A, but it's not recommended for high-current applications due to thermal limitations. For high-current applications, consider using a heat sink or a more suitable regulator like the LM338.

  • The output voltage of the LM317 can be adjusted by using a resistive divider network between the output and adjustment pins. The formula to calculate the output voltage is Vout = 1.25V * (1 + R2/R1), where R1 and R2 are the resistors in the divider network.

  • The minimum input-to-output voltage differential required for the LM317 to operate is 3V. This means that the input voltage must be at least 3V higher than the output voltage.

  • No, the LM317 is not a low-dropout regulator (LDO). It has a relatively high dropout voltage, which means it requires a higher input voltage to maintain regulation. For LDO applications, consider using a more suitable regulator like the LP2985.
