LD1117D33CTR datasheet by STMicroelectronics

LD1117D33CTR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LD1117D33CTR?
  The maximum input voltage that can be applied to the LD1117D33CTR is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• How do I ensure the stability of the output voltage?
  To ensure the 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 LD1117D33CTR can provide?
  The maximum output current that the LD1117D33CTR can provide is 800mA, but it's recommended to keep it below 500mA for optimal performance and to prevent overheating.
• How do I protect the LD1117D33CTR from overheating?
  To protect the LD1117D33CTR from overheating, it's recommended to provide a heat sink or a thermal pad, and to keep the ambient temperature below 70°C. Also, ensure that the input voltage is within the recommended range and the output current is within the maximum rating.
• Can I use the LD1117D33CTR in a high-temperature environment?
  The LD1117D33CTR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases. Consult the datasheet for more information on thermal derating.
