LM317LM/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 voltage required for the LM317 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 LM317 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 LM317 is typically around 2V, which means the input voltage should be at least 2V higher than the desired output voltage.
