MAX755CSA+ datasheet by Maxim Integrated Products

MAX755CSA+ Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the MAX755CSA+?
  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 ripple and improve output stability.
• How do I ensure the MAX755CSA+ is stable and does not oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient input capacitor, and keep the output capacitor value within the recommended range. Also, avoid using long traces and minimize the distance between the input and output capacitors.
• What is the maximum output current capability of the MAX755CSA+?
  The maximum output current capability of the MAX755CSA+ is 150mA. However, the actual output current capability may be limited by the input voltage, output voltage, and thermal considerations.
• Can I use the MAX755CSA+ in a high-temperature environment?
  The MAX755CSA+ is rated for operation up to 125°C. However, the device's performance and reliability may be affected at high temperatures. It's recommended to derate the output current and ensure proper thermal management to prevent overheating.
• How do I calculate the output voltage of the MAX755CSA+?
  The output voltage of the MAX755CSA+ can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.25V), R1 is the feedback resistor, and R2 is the divider resistor.
