L5987ATR Frequently Asked Questions (FAQs)

  • The L5987ATR can handle a maximum input voltage of 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
  • To ensure the stability of the output voltage, make sure to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a sufficient capacitance value. A 10uF to 22uF ceramic capacitor is recommended.
  • The minimum input voltage required for the L5987ATR to operate is 6.5V, but it's recommended to keep it above 7V for optimal performance.
  • The L5987ATR is rated for operation up to 150°C, but it's recommended to keep the junction temperature below 125°C for optimal performance and reliability.
  • The output voltage of the L5987ATR can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (1.25V), and R1 and R2 are the resistors used in the feedback network.
