LM5117PMHE/NOPB Frequently Asked Questions (FAQs)

  • The LM5117 can handle input voltages up to 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10nF capacitor between the VIN and GND pins.
  • The minimum input capacitance required is 10uF, but it's recommended to use a 22uF or larger capacitor to ensure stable operation.
  • The LM5117 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliable operation.
  • The output voltage of the LM5117 is set by the resistive divider network between the FB and GND pins. Use the formula: Vout = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
