LD1117DT50TR Frequently Asked Questions (FAQ)

  • 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 dropout voltage is typically around 1.5V, which means the input voltage should be at least 1.5V higher than the output voltage for proper regulation.

  • The LD1117DT50TR is rated for operation up to 125°C, but the junction temperature should be kept below 150°C to ensure reliability and prevent thermal shutdown.

  • Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
