LT1117IST-2.85#PBF Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LT1117IST-2.85 is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.

  • While the LT1117IST-2.85 can deliver up to 1A of output current, it's not designed for high-current applications. For high-current requirements, consider using a different regulator like the LT1085 or LT1086.

  • To ensure the LT1117IST-2.85 operates within its thermal limits, make sure to provide adequate heat sinking, keep the input voltage as low as possible, and avoid high ambient temperatures. You can also use thermal simulation tools to estimate the junction temperature.

  • No, the LT1117IST-2.85 is a linear regulator and not designed for switching regulator applications. It's not suitable for high-frequency switching and may not provide the required efficiency or stability.

  • The minimum input voltage required for the LT1117IST-2.85 to operate is 2.85V + Vdropout, where Vdropout is the dropout voltage, typically around 1.2V. So, the minimum input voltage would be around 4.05V.
