L4940V85 Frequently Asked Questions (FAQs)

  • The L4940V85 can handle input voltages up to 40V, but it's recommended to keep it below 30V for optimal performance and reliability.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the regulator to minimize parasitic inductance.
  • The L4940V85 requires a minimum input voltage of 7V to function properly, but it's recommended to keep it above 8V for optimal performance.
  • The L4940V85 is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability.
  • The power dissipation of the L4940V85 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.
