L5980TR datasheet by STMicroelectronics

L5980TR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the L5980TR can handle?
  The L5980TR can handle a maximum input voltage of 40V, but it's recommended to keep it below 36V for reliable operation.
• How do I ensure the L5980TR is stable and doesn't oscillate?
  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.
• What is the minimum input voltage required for the L5980TR to operate?
  The L5980TR can operate with an input voltage as low as 6.5V, but the output voltage regulation may not be guaranteed below 8V.
• Can I use the L5980TR in a high-temperature environment?
  The L5980TR is rated for operation up to 150°C, but the maximum junction temperature (Tj) should not exceed 150°C. Ensure proper heat sinking and thermal management to prevent overheating.
• How do I calculate the output voltage of the L5980TR?
  The output voltage (Vout) 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 resistors in the feedback network.
