L7805CD2T datasheet by STMicroelectronics

L7805CD2T Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L7805CD2T?
  The maximum input voltage that can be applied to the L7805CD2T is 35V, but it's recommended to keep it below 25V for reliable operation.
• How do I ensure the L7805CD2T is stable and doesn't oscillate?
  To ensure stability, a minimum output capacitance of 10uF is recommended, and the input capacitor should be at least 10uF with an ESR of less than 5 ohms.
• What is the maximum current that the L7805CD2T can supply?
  The L7805CD2T can supply up to 1A of output current, but it's recommended to derate the current based on the ambient temperature and input voltage.
• How do I protect the L7805CD2T from overheating?
  To protect the L7805CD2T from overheating, ensure good heat sinking, keep the ambient temperature below 50°C, and avoid high input voltages and output currents.
• Can I use the L7805CD2T in a switching regulator application?
  No, the L7805CD2T is a linear voltage regulator and not suitable for switching regulator applications. It's designed for linear voltage regulation only.
