REG1117A-1.8 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the REG1117A-1.8 is 15V. Exceeding this voltage may damage the device.
  • The REG1117A-1.8 can supply up to 1A of output current. However, the maximum current is dependent on the input voltage, output voltage, and ambient temperature.
  • The dropout voltage of the REG1117A-1.8 is typically around 1.5V. This means that the input voltage must be at least 1.5V higher than the output voltage to maintain regulation.
  • Yes, the REG1117A-1.8 has built-in short-circuit protection. If the output is short-circuited, the device will limit the output current to prevent damage.
  • The REG1117A-1.8 is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures.
