L7985ATR Frequently Asked Questions (FAQs)

  • The L7985ATR can handle a maximum input voltage of 30V, but it's recommended to keep it below 25V for reliable operation.
  • To ensure stability, make sure to use the recommended output capacitor value and type, and keep the input capacitor value within the recommended range. Also, ensure the PCB layout is well-designed and follows good practices.
  • The minimum input voltage required for the L7985ATR to operate is 7V, but it's recommended to keep it above 8V for reliable operation.
  • The L7985ATR is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
  • The output voltage of the L7985ATR is adjustable and 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.
