REF3033AIDBZT Frequently Asked Questions (FAQ)

  • A good PCB layout practice is to keep the REF3033AIDBZT away from high-current carrying traces and noisy components. Use a solid ground plane and decouple the REF3033AIDBZT with a 10uF capacitor to minimize noise.

  • To ensure stability and accuracy over temperature, use a stable input voltage, decouple the REF3033AIDBZT with a 10uF capacitor, and keep the device away from high-temperature sources. Also, consider using a thermally conductive material to dissipate heat.

  • The recommended input voltage range for the REF3033AIDBZT is 4.5V to 18V. Operating outside this range may affect the accuracy and stability of the voltage reference.

  • The output voltage tolerance of the REF3033AIDBZT can be calculated by adding the initial accuracy (±0.05% for the REF3033AIDBZT) to the temperature coefficient (±10ppm/°C). This will give you the total output voltage tolerance over the operating temperature range.

  • No, the REF3033AIDBZT is a voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, not to regulate voltage. Using it as a voltage regulator may lead to instability and inaccurate voltage output.
