LT3080EST Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LT3080EST is 36V, but it's recommended to keep it below 30V for reliable operation.

  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the output voltage sense lines short and away from noise sources.

  • Yes, the LT3080EST is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Make sure to follow proper thermal design and heat sinking to ensure reliable operation.

  • The output voltage of the LT3080EST can be adjusted by changing the value of the feedback resistors (R1 and R2) according to the formula: Vout = 0.5V x (1 + R2/R1).

  • The LT3080EST can maintain regulation down to a minimum load current of 1mA, but it's recommended to have a minimum load current of 10mA for optimal performance.
