MCP1811AT-028/TT Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 1uF to 10uF, with a voltage rating of at least 6.3V. A larger capacitor value can be used for improved noise filtering and stability.
  • To ensure the output voltage is stable and accurate, make sure to follow the recommended PCB layout guidelines, use a stable input voltage, and add a 10nF to 100nF capacitor at the output pin to filter out noise and oscillations.
  • The maximum output current capability of the MCP1811AT-028/TT is 1A. However, it's recommended to derate the output current to 0.8A to ensure reliable operation and to prevent overheating.
  • To protect the MCP1811AT-028/TT from input voltage transients and surges, add a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input pin to limit the voltage to within the recommended operating range.
  • The thermal shutdown temperature of the MCP1811AT-028/TT is typically around 150°C to 160°C. When the junction temperature exceeds this threshold, the device will shut down to prevent damage.
