L4931CV50 Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the L4931CV50 is 26V, although it's recommended to keep it below 20V for optimal performance and reliability.

  • To ensure stability, make sure to use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 1 ohm, and keep the input capacitance as close to the regulator as possible.

  • The minimum input voltage required for the L4931CV50 to operate is 6.5V, although it's recommended to keep it above 7V for optimal performance.

  • Yes, the L4931CV50 can operate in high-temperature environments up to 150°C, but the output current may need to be derated to prevent overheating. Consult the datasheet for specific derating curves.

  • The power dissipation of the L4931CV50 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.
