LD1117S12CTR datasheet by STMicroelectronics

LD1117S12CTR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LD1117S12CTR?
  The maximum input voltage that can be applied to the LD1117S12CTR is 15V, but it's recommended to keep it below 13.5V for reliable operation.
• How do I ensure stability of the output voltage?
  To ensure stability of the output voltage, it's recommended to use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 1 ohm, and to keep the input capacitance as close to the regulator as possible.
• What is the maximum output current that the LD1117S12CTR can provide?
  The maximum output current that the LD1117S12CTR can provide is 800mA, but it's recommended to keep it below 500mA for reliable operation and to prevent overheating.
• How do I protect the LD1117S12CTR from overheating?
  To protect the LD1117S12CTR from overheating, it's recommended to provide adequate heat sinking, keep the device away from high-temperature sources, and ensure good airflow around the device.
• Can I use the LD1117S12CTR in a high-temperature environment?
  The LD1117S12CTR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to prevent overheating and ensure reliable operation.
