MP2451DT-LF-Z datasheet by Monolithic Power Systems

MP2451DT-LF-Z Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the MP2451DT-LF-Z can handle?
  The maximum input voltage is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the output voltage within the recommended range of 0.8V to 15V.
• What is the maximum output current that the MP2451DT-LF-Z can provide?
  The maximum output current is 1.5A, but it's recommended to keep it below 1.2A for optimal performance and reliability.
• How do I adjust the output voltage?
  The output voltage can be adjusted by using a resistive divider network between the output and the FB pin. The recommended resistors are R1 = 10kohm and R2 = 2.2kohm for a 3.3V output.
• What is the purpose of the EN pin?
  The EN (enable) pin is used to turn the regulator on or off. When EN is high, the regulator is enabled, and when EN is low, the regulator is disabled.
