LM317HVH/NOPB datasheet by Texas Instruments

LM317HVH/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM317HVH/NOPB can handle?
  The LM317HVH/NOPB can handle input voltages up to 60V, making it suitable for high-voltage applications.
• How do I ensure stability when using the LM317HVH/NOPB?
  To ensure stability, use a minimum output capacitance of 1uF and a minimum input capacitance of 0.1uF, and keep the output voltage at least 3V below the input voltage.
• Can I use the LM317HVH/NOPB in a high-temperature environment?
  Yes, the LM317HVH/NOPB is rated for operation up to 125°C, making it suitable for high-temperature applications. However, ensure proper thermal management to prevent overheating.
• How do I adjust the output voltage of the LM317HVH/NOPB?
  The output voltage 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).
• Is the LM317HVH/NOPB suitable for high-current applications?
  The LM317HVH/NOPB is rated for up to 1.5A of output current, making it suitable for moderate-current applications. However, for high-current applications, consider using a more robust voltage regulator or a current-boosting circuit.
