L5985TR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the L5985TR is 30V, but it's recommended to keep it below 28V for reliable operation.
  • To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor, and add a compensation network if necessary.
  • The minimum input voltage required for the L5985TR to operate is 7V, but it's recommended to keep it above 8V for reliable startup and operation.
  • Yes, the L5985TR can operate in a high-temperature environment up to 150°C, but the maximum junction temperature should not exceed 125°C for reliable operation.
  • The output voltage of the L5985TR can be calculated using the formula: Vout = Vref x (1 + R2/R1), where Vref is the internal reference voltage (2.5V) and R1 and R2 are the feedback resistors.
