MCP1790-3002E/DB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the MCP1790-3002E/DB is 18V, but it's recommended to operate within the specified input voltage range of 6.5V to 15V for optimal performance and reliability.
  • To ensure the output voltage is stable and accurate, make sure to follow the recommended layout and component placement guidelines, use a stable input voltage, and add sufficient decoupling capacitors at the input and output pins. Additionally, ensure that the output capacitor is within the recommended range of 10uF to 100uF.
  • The minimum ESR required for the output capacitor is 50mΩ. Using a capacitor with a lower ESR can cause instability and affect the regulator's performance.
  • The MCP1790-3002E/DB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation. Consult the datasheet for specific derating guidelines.
  • To protect the MCP1790-3002E/DB from input voltage transients and surges, add a TVS (Transient Voltage Suppressor) diode or a voltage clamp at the input pin. This will help absorb or clamp the transient voltage and prevent damage to the regulator.
