L5983TR Frequently Asked Questions (FAQs)

  • The L5983TR can handle a maximum input voltage of 30V, but it's recommended to keep it below 28V for reliable operation.
  • To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor, and add a compensation network (Rc and Cc) as described in the datasheet.
  • The L5983TR can operate with an input voltage as low as 7V, but the output voltage regulation may not be guaranteed below 8V.
  • The L5983TR is rated for operation up to 150°C, but the maximum junction temperature (Tj) should not exceed 150°C. Ensure proper thermal management and consider derating the device for high-temperature applications.
  • The output voltage (Vout) can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (2.5V), and R1 and R2 are the feedback resistors.
