LT3091HR#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT3091HR is 40V, but it's recommended to keep it below 36V 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 close to the output pin to minimize parasitic inductance.
  • The maximum output current that the LT3091HR can deliver is 1.5A, but it's recommended to keep it below 1.2A for reliable operation and to prevent overheating.
  • The output voltage of the LT3091HR can be adjusted by using a resistive divider network between the output pin and the adjust pin. The output voltage can be calculated using the formula: Vout = 1.22 x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
  • 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. This pin can be used to implement power sequencing or to turn off the regulator when not in use.
