L5987A Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the L5987A is 28V, but it's recommended to keep it below 24V for reliable operation.
  • To ensure stability, make sure to follow the recommended layout and component selection guidelines, and add a 10nF capacitor between the VIN and GND pins to filter out high-frequency noise.
  • The minimum input voltage required for the L5987A to operate is 6.5V, but it's recommended to keep it above 7V for reliable startup and operation.
  • Yes, the L5987A can operate in a high-temperature environment up to 150°C, but the maximum junction temperature (TJ) should not exceed 150°C. Make sure to follow the recommended thermal management guidelines to ensure reliable operation.
  • The output voltage of the L5987A can be calculated using the formula: VOUT = (1 + R2/R1) * VREF, where R1 and R2 are the resistors connected to the FB pin, and VREF is the internal reference voltage (2.5V).
