REG1117-2.85 Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the REG1117-2.85 is 15V. Exceeding this voltage may damage the device.

  • The REG1117-2.85 can supply up to 1A of output current. However, the maximum current is limited by the thermal dissipation of the package and the input voltage.

  • The dropout voltage of the REG1117-2.85 is typically around 1.5V. This means that the input voltage must be at least 1.5V higher than the output voltage to maintain regulation.

  • The REG1117-2.85 is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and ensure proper thermal management.

  • To ensure stability, a minimum output capacitance of 10uF is recommended. Additionally, the input capacitor should be at least 1uF to prevent oscillations.
