LT3081IR#TRPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT3081 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 with an ESR of 0.05Ω or less, and to place the capacitor close to the output pin.
  • While the LT3081 can deliver up to 1.1A of output current, it's not recommended for high-current applications due to thermal limitations. For high-current applications, consider using a switching regulator or a more suitable linear regulator.
  • The output voltage of the LT3081 can be adjusted by using a resistive divider network between the output and the ADJ pin. The ratio of the resistors determines the output voltage, which can be calculated using the formula: Vout = 1.2V x (1 + R1/R2).
  • The LT3081 is not AEC-Q100 qualified, so it's not recommended for automotive applications. For automotive applications, consider using a qualified regulator such as the LT1085 or LT1965.
