LD3985J18R Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LD3985J18R is 26V, although the recommended operating input voltage range is 6.5V to 24V.
  • To ensure stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 1 ohm, and to place the capacitor close to the output pin of the device.
  • The maximum output current that the LD3985J18R can deliver is 1.5A, although the device can deliver up to 2A for short periods of time during startup or under fault conditions.
  • To protect the LD3985J18R from overheating, it is recommended to provide adequate heat sinking, such as a copper plane or a heat sink, and to ensure good airflow around the device. The device has a built-in thermal shutdown feature that will turn off the device if the junction temperature exceeds 150°C.
  • The LD3985J18R is rated for operation up to 125°C, but the device's performance and reliability may be affected at high temperatures. It is recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
