LD1086V18-DG Frequently Asked Questions (FAQs)

  • The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
  • 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 a minimum input capacitance of 1uF.
  • The dropout voltage is typically around 1.5V, which means the input voltage must be at least 1.5V higher than the output voltage for the regulator to function properly.
  • The LD1086V18-DG is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and input voltage to ensure reliable operation.
  • Power dissipation 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.
