LM317HVT/NOPB Frequently Asked Questions (FAQs)

  • The LM317HVT can handle input voltages up to 60V, but it's recommended to keep it below 50V for reliable operation.
  • The output voltage of the LM317HVT 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 x (1 + R2/R1).
  • The LM317HVT requires a minimum load current of 3.5mA to maintain regulation. If the load current is less than this, the output voltage may not be regulated properly.
  • The LM317HVT is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.
  • To protect the LM317HVT from input voltage transients, it's recommended to use a transient voltage suppressor (TVS) diode or a voltage clamp circuit at the input.
