LTC7817IUHF#WPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC7817IUHF is 40V, but it's recommended to keep it below 36V for reliable operation.
  • To ensure stability, it's essential to follow the recommended layout and component selection guidelines, including the use of a suitable output capacitor and a low-ESR input capacitor.
  • The maximum output current that the LTC7817IUHF can deliver is 1.5A, but it's recommended to derate the output current based on the ambient temperature and the input voltage.
  • The output voltage of the LTC7817IUHF can be programmed using an external resistor divider network connected to the FB pin, with a range of 0.8V to 15V.
  • The EN (enable) pin is used to turn the regulator on or off. When the EN pin is pulled high, the regulator is enabled, and when it's pulled low, the regulator is disabled.
