LD1117DT25CTR datasheet by STMicroelectronics

LD1117DT25CTR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LD1117DT25CTR?
  The maximum input voltage that can be applied to the LD1117DT25CTR 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 essential 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 minimum input voltage required for the LD1117DT25CTR to function properly?
  The minimum input voltage required for the LD1117DT25CTR to function properly is 7.5V, but it's recommended to keep it above 8V for optimal performance.
• Can I use the LD1117DT25CTR in a high-temperature environment?
  The LD1117DT25CTR is rated for operation up to 125°C, but it's essential to ensure proper heat sinking and thermal management to prevent overheating, especially in high-temperature environments.
• How do I protect the LD1117DT25CTR from input voltage transients?
  To protect the LD1117DT25CTR from input voltage transients, it's recommended to use a TVS (Transient Voltage Suppressor) diode or a varistor in parallel with the input capacitor to absorb voltage spikes and surges.
