LM317MDT Frequently Asked Questions (FAQ)

  • The minimum input voltage required for the LM317MDT to operate is 3V above the output voltage. For example, if the output voltage is 5V, the minimum input voltage should be at least 8V.

  • To ensure stability and prevent oscillations, a minimum output capacitance of 1uF is recommended. Additionally, the input capacitor should be at least 0.1uF and the ESR (Equivalent Series Resistance) of the output capacitor should be less than 5 ohms.

  • The maximum output current that the LM317MDT can deliver is 1.5A. However, it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.

  • No, the LM317MDT is a positive voltage regulator and cannot be used as a negative voltage regulator. For negative voltage regulation, a different regulator such as the LM337 is required.

  • The output voltage of the LM317MDT can be adjusted by using a resistive divider network between the output and the adjust pin. The output voltage is determined by the ratio of the resistors and the reference voltage (1.25V) of the LM317MDT.
