MAX811SEUS-T datasheet by Maxim Integrated Products

MAX811SEUS-T Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the MAX811SEUS-T?
  The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements.
• How do I ensure the MAX811SEUS-T is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and add a 1kΩ to 10kΩ resistor in series with the output capacitor.
• What is the maximum input voltage that the MAX811SEUS-T can handle?
  The maximum input voltage is 28V, but it's recommended to keep the input voltage below 24V for optimal performance and reliability.
• Can I use the MAX811SEUS-T in a high-temperature environment?
  The MAX811SEUS-T is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability.
• How do I calculate the output voltage of the MAX811SEUS-T?
  The output voltage is set by the resistive divider network connected to the FB pin. Use the formula: Vout = 1.25V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
