LM34910CSD/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM34910CSD/NOPB is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the output capacitor should be placed as close to the output pin as possible.
  • The maximum output current that the LM34910CSD/NOPB can deliver is 2A, but it's recommended to keep it below 1.5A for reliable operation and to prevent overheating.
  • The output voltage of the LM34910CSD/NOPB can be calculated using the formula: Vout = (R1/R2) * (1.25V), where R1 and R2 are the resistors connected to the FB pin.
  • The EN (Enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
