LD1086V18 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LD1086V18 is 25V, but it's recommended to keep it below 20V 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 LD1086V18 is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. It's essential to ensure proper heat sinking and thermal management to prevent overheating.
  • The power dissipation (PD) 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. Make sure to consider the thermal resistance (RthJA) and the maximum junction temperature (TJ) when calculating the power dissipation.
  • The LD1086V18 is capable of delivering up to 1.5A of output current, but it's essential to ensure proper heat sinking and thermal management to prevent overheating. For high-current applications, it's recommended to use a heat sink with a thermal resistance of less than 10°C/W.
