LT1171CQ#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT1171CQ is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
  • To ensure stability in the output voltage, 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 LT1171CQ can deliver is 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
  • The output voltage of the LT1171CQ 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 = 1.25 x (1 + R1/R2).
  • The adjust pin on the LT1171CQ is used to adjust the output voltage of the regulator. It's connected to a resistive divider network that sets the output voltage. It's also used to provide a feedback path for the internal error amplifier.
