L4981AD013TR datasheet by STMicroelectronics

L4981AD013TR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L4981AD013TR?
  The maximum input voltage that can be applied to the L4981AD013TR is 28V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the stability of the output voltage in the L4981AD013TR?
  To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a minimum capacitance of 10uF. Additionally, the input capacitor should be at least 10uF with a low ESR.
• What is the maximum output current that the L4981AD013TR can deliver?
  The maximum output current that the L4981AD013TR can deliver is 1.5A, but it's recommended to keep it below 1.2A for reliable operation and to prevent overheating.
• How do I protect the L4981AD013TR from overheating?
  To protect the L4981AD013TR from overheating, ensure good airflow around the device, use a heat sink if necessary, and keep the output current below the recommended maximum value. Also, avoid operating the device in high ambient temperatures.
• Can I use the L4981AD013TR in a high-reliability application?
  Yes, the L4981AD013TR is suitable for high-reliability applications due to its high MTBF (Mean Time Between Failures) and low FIT (Failure In Time) rate. However, it's essential to follow proper design and manufacturing guidelines to ensure the reliability of the final product.
