L4931ABD120TR Frequently Asked Questions (FAQs)

  • The maximum input voltage for the L4931ABD120TR is 30V, but it's recommended to keep it below 25V for reliable operation.
  • To ensure stability, a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 1 ohm is recommended. Additionally, the input capacitor should be at least 1uF with an ESR of less than 5 ohms.
  • The dropout voltage of the L4931ABD120TR is typically around 1.5V, but it can be as low as 1.2V for a 1A load current.
  • The L4931ABD120TR is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. It's essential to ensure proper heat sinking and thermal management to prevent overheating.
  • The power dissipation of the L4931ABD120TR 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.
