LMR38025FDRRR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LMR38025FDRRR is 26V, although it's recommended to keep it below 25V for reliable operation.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF with an ESR of 0.1Ω to 10Ω, and keep the input capacitance as close to the regulator as possible.
  • The minimum input voltage required for the LMR38025FDRRR to operate is 6.5V, although it's recommended to keep it above 7V for reliable operation.
  • The LMR38025FDRRR is rated for operation up to 125°C, but its performance may degrade at high temperatures. Make sure to derate the output current and consider using a heat sink if operating in high-temperature environments.
  • The power dissipation of the LMR38025FDRRR can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
