LT3091IR#PBF Frequently Asked Questions (FAQs)

  • The LT3091 can handle input voltages up to 40V, but it's recommended to keep it below 36V for optimal performance and reliability.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR capacitor for the input capacitor (Cin).
  • The LT3091 can deliver up to 1.5A of output current, but it's recommended to keep it below 1.2A for optimal performance and reliability.
  • The output voltage can be adjusted by using a resistive divider network (R1 and R2) connected to the FB pin. The output voltage is determined by the ratio of R1 to R2.
  • The EN (enable) pin is used to turn the regulator on or off. When EN is high, the regulator is enabled, and when EN is low, the regulator is disabled.
