DL4148 datasheet by Micro Commercial Components

DL4148 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the DL4148 can handle?
  The maximum input voltage that the DL4148 can handle is 35V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) should be less than 5 ohms.
• What is the maximum output current that the DL4148 can provide?
  The maximum output current that the DL4148 can provide is 1.5A, but it's recommended to keep it below 1.2A for reliable operation.
• How does the DL4148 handle overcurrent protection?
  The DL4148 has built-in overcurrent protection, which limits the output current to prevent damage to the device. The overcurrent threshold is typically around 2.5A.
• What is the dropout voltage of the DL4148?
  The dropout voltage of the DL4148 is around 1.5V, which means that the input voltage should be at least 1.5V higher than the output voltage for proper regulation.
