MP1482DS-LF datasheet by Monolithic Power Systems

MP1482DS-LF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the MP1482DS-LF can handle?
  The MP1482DS-LF can handle a maximum input voltage of 28V, but it's recommended to keep it below 24V 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 capacitor close to the IC to minimize parasitic inductance.
• What is the maximum output current that the MP1482DS-LF can provide?
  The MP1482DS-LF can provide a maximum output current of 2A, but it's recommended to keep it below 1.5A 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 ratio of the resistors determines the output voltage, which can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2.
• What is the purpose of the EN pin?
  The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
