LD1117AS33TR 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.
  • To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) should be between 0.3Ω and 10Ω.
  • The maximum output current is 800mA, but it's recommended to keep it below 500mA for optimal performance and to prevent overheating.
  • To prevent overheating, ensure good thermal conduction by using a heat sink or a thermal pad, and keep the ambient temperature below 70°C.
  • The LD1117AS33TR is rated for operation up to 125°C, but the output current should be derated above 85°C to prevent overheating.
