LD1117SC-R datasheet by STMicroelectronics

LD1117SC-R Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LD1117SC-R?
  The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• How do I ensure the LD1117SC-R is stable and doesn't oscillate?
  To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 1 ohm, and keep the input capacitance as close to the regulator as possible.
• What is the minimum input voltage required for the LD1117SC-R to function properly?
  The minimum input voltage is 3.5V, but it's recommended to keep it above 4V for optimal performance and to ensure the output voltage remains within regulation.
• Can I use the LD1117SC-R in a high-temperature environment?
  The LD1117SC-R is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Ensure proper heat sinking and thermal management to prevent overheating.
• How do I calculate the power dissipation of the LD1117SC-R?
  Power dissipation (PD) 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.
