MP3389EF-LF-Z Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the MP3389EF-LF-Z can handle?
  The MP3389EF-LF-Z can handle a maximum input voltage of 24V, but it's recommended to keep it below 20V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the input voltage is within the recommended range and the output current is within the specified limit.
• What is the maximum output current that the MP3389EF-LF-Z can provide?
  The MP3389EF-LF-Z can provide a maximum output current of 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
• How do I adjust the output voltage of the MP3389EF-LF-Z?
  The output voltage of the MP3389EF-LF-Z can be adjusted by using a resistive divider network between the output pin and the ground pin. The output voltage can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
• What is the thermal shutdown temperature of the MP3389EF-LF-Z?
  The thermal shutdown temperature of the MP3389EF-LF-Z is typically around 150°C, but it can vary depending on the specific application and operating conditions.
