MP1517DR-LF-Z datasheet by Monolithic Power Systems

MP1517DR-LF-Z Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the MP1517DR-LF-Z can handle?
  The maximum input voltage is 23V, 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 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 MP1517DR-LF-Z can deliver?
  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 resistor divider network between the output and the ADJ pin. The formula to calculate the output voltage is Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
• 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.
