uA7805CKC Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the UA7805CKC can handle?
  The UA7805CKC can handle input voltages up to 35V, but it's recommended to keep the input voltage at least 2V higher than the output voltage (5V) to ensure proper regulation.
• How much current can the UA7805CKC supply?
  The UA7805CKC can supply up to 1A of output current, but it's recommended to keep the output current below 500mA for optimal performance and to prevent overheating.
• What is the dropout voltage of the UA7805CKC?
  The dropout voltage of the UA7805CKC is typically around 2V, which means that the input voltage must be at least 2V higher than the output voltage (5V) to ensure proper regulation.
• Is the UA7805CKC a low-dropout regulator (LDO)?
  No, the UA7805CKC is not a low-dropout regulator (LDO). It has a relatively high dropout voltage of 2V, which means it's not suitable for applications where the input voltage is close to the output voltage.
• Can I use the UA7805CKC in a high-temperature environment?
  The UA7805CKC is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to use a heat sink or to derate the output current to prevent overheating.
