MAX811TEUS-T Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the MAX811TEUS-T?
  The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help to reduce input voltage ripple and improve output voltage regulation.
• How do I ensure the MAX811TEUS-T is stable and does not 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 to prevent oscillation.
• What is the maximum input voltage that the MAX811TEUS-T can handle?
  The MAX811TEUS-T can handle input voltages up to 15V, but it's recommended to operate within the specified input voltage range of 4.5V to 14V for optimal performance and reliability.
• Can I use the MAX811TEUS-T in a high-temperature environment?
  The MAX811TEUS-T is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliable operation and prevent overheating.
• How do I calculate the output voltage of the MAX811TEUS-T?
  The output voltage of the MAX811TEUS-T is adjustable using the FB (feedback) pin. The output voltage can be calculated using the formula: Vout = 1.25V x (R1/R2 + 1), where R1 and R2 are the resistors connected to the FB pin.
