LM3404HVMR datasheet by Texas Instruments

LM3404HVMR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM3404HVMR?
  The maximum input voltage that can be applied to the LM3404HVMR is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the LM3404HVMR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a minimum output capacitance of 10uF, and avoid using long traces or wires that can cause parasitic inductance.
• Can I use the LM3404HVMR in a high-temperature environment?
  Yes, the LM3404HVMR is rated for operation up to 150°C, but the maximum junction temperature (TJ) should not exceed 125°C. Make sure to follow the thermal design guidelines and use a suitable heat sink if necessary.
• How do I calculate the output voltage of the LM3404HVMR?
  The output voltage of the LM3404HVMR can be calculated using the formula: VOUT = 1.25V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
• Is the LM3404HVMR suitable for high-current applications?
  The LM3404HVMR is capable of delivering up to 3A of output current, but it's recommended to derate the current based on the ambient temperature and the thermal design of the system.
