REG1117-3.3/2K5 Frequently Asked Questions (FAQs)

  • The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
  • The REG1117-3.3/2K5 can supply up to 1A of output current, but it's recommended to keep it below 800mA for optimal performance and to prevent overheating.
  • The dropout voltage is typically around 1.5V, which means the input voltage should be at least 4.8V to ensure a stable 3.3V output.
  • Yes, the REG1117-3.3/2K5 is a low-dropout regulator (LDO), which means it can operate with a smaller input-to-output voltage differential compared to traditional linear regulators.
  • The thermal shutdown temperature is typically around 150°C, which means the regulator will shut down if the junction temperature exceeds this value to prevent damage.
