LD1117S12TR Frequently Asked Questions (FAQ)

  • The maximum input voltage is 15V, but it's recommended to keep it below 13.5V for reliable operation.

  • To ensure stability, a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 1 ohm is recommended.

  • The maximum output current is 800mA, but it's recommended to keep it below 500mA for reliable operation and to prevent overheating.

  • To prevent overheating, ensure good thermal conduction by mounting the device on a heat sink or a PCB with a large copper area, and keep the ambient temperature below 70°C.

  • The LD1117S12TR is rated for operation up to 125°C, but the output current should be derated to 300mA at high temperatures (above 85°C) to prevent overheating.
