MCP1703T-4002E/DB Frequently Asked Questions (FAQ)

  • The maximum input voltage is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.

  • To ensure a stable and accurate output voltage, make sure to use a suitable output capacitor (e.g., 1uF to 10uF) and keep the input voltage within the recommended range. Also, minimize noise and ripple on the input voltage.

  • The dropout voltage is typically around 300mV to 400mV, which means the input voltage should be at least 400mV higher than the output voltage for proper regulation.

  • The MCP1703T-4002E/DB is rated for operation up to 125°C, but it's essential to consider the thermal resistance and power dissipation when designing for high-temperature applications.

  • Power dissipation (PD) 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.
