MAX881REUB+ datasheet by Maxim Integrated Products

MAX881REUB+ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the MAX881REUB+ can handle?
  The MAX881REUB+ can handle input voltages up to 28V, but it's recommended to operate within the 7V to 24V range for optimal performance.
• How do I ensure the stability of the output voltage?
  To ensure stability, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the output capacitor should be placed as close to the output pin as possible.
• What is the purpose of the EN (enable) pin?
  The EN pin is used to enable or disable the regulator. When the EN pin is pulled low, the regulator is shut down, and the output voltage is disconnected from the input voltage. This feature can be used to reduce power consumption in standby mode.
• How do I choose the right output capacitor for the MAX881REUB+?
  The output capacitor should be chosen based on the output voltage and current requirements. A general rule of thumb is to use a capacitor with a value of at least 10uF and a voltage rating of 1.5 to 2 times the output voltage.
• What is the thermal shutdown temperature of the MAX881REUB+?
  The MAX881REUB+ has a thermal shutdown temperature of 150°C. If the junction temperature exceeds this value, the regulator will shut down to prevent damage.
