MCP1703-4002E/DB Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the MCP1703-4002E/DB is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.

  • To ensure the stability of the output voltage, it's recommended to use a minimum output capacitance of 1uF and a maximum ESR of 1.3 ohms. Additionally, the input capacitor should be at least 1uF with an ESR of 1 ohm or less.

  • The maximum output current that the MCP1703-4002E/DB can provide is 250mA. However, the output current should be derated based on the input voltage and ambient temperature to prevent overheating.

  • The power dissipation of the MCP1703-4002E/DB can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.

  • The thermal shutdown temperature of the MCP1703-4002E/DB is typically around 150°C. When the junction temperature exceeds this value, the device will shut down to prevent damage.
