LD1117AG-33-AA3-A-R Frequently Asked Questions (FAQs)

  • The maximum input voltage is 15V, but it's recommended to keep it below 12V for stable operation.
  • The operating junction temperature range is -40°C to 125°C, but the output voltage regulation and other parameters may degrade at high temperatures. It's recommended to keep the junction temperature below 85°C for optimal performance.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 5 ohms. Also, keep the input and output capacitors close to the regulator to minimize parasitic inductance.
  • No, the LD1117AG-33-AA3-A-R is a linear voltage regulator and not suitable for switching regulator applications. It's designed to provide a stable output voltage in linear mode only.
  • The typical dropout voltage is around 1.5V, which means the input voltage should be at least 1.5V higher than the output voltage for proper regulation.
