LD1086V25 datasheet by STMicroelectronics

LD1086V25 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LD1086V25?
  The maximum input voltage that can be applied to the LD1086V25 is 30V, but it's recommended to keep it below 28V for reliable operation.
• How do I ensure stability of the output voltage with the LD1086V25?
  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.
• Can I use the LD1086V25 in a high-temperature environment?
  The LD1086V25 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.
• How do I calculate the power dissipation of the LD1086V25?
  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.
• Is the LD1086V25 suitable for high-current applications?
  The LD1086V25 is capable of delivering up to 3A of output current, but it's essential to ensure proper heat sinking and thermal management to prevent overheating. Additionally, the input voltage and output current should be within the recommended operating conditions to prevent overheating and ensure reliable operation.
