MCP1703-3302E/DB Frequently Asked Questions (FAQ)

  • The maximum input voltage is 16V, but it's recommended to keep it below 15V for reliable operation.

  • Use a minimum of 1uF capacitor on the input and output pins, and ensure the PCB layout is designed to minimize noise and EMI.

  • Yes, but the device is only specified to operate up to 125°C. Above this temperature, the device's performance and reliability may degrade.

  • The maximum output current is 250mA, but this can be limited by the input voltage, output voltage, and thermal considerations.

  • Yes, the MCP1703-3302E/DB is an LDO, which means it can operate with a relatively small input-to-output voltage differential (around 1.5V).
