REF3033AIDBZR Frequently Asked Questions (FAQ)

  • A good PCB layout practice is to keep the REF3033AIDBZR away from high-current carrying traces and noisy components. Use a solid ground plane and keep the input and output traces short and direct. Additionally, decouple the input voltage with a 10uF capacitor and use a 10nF capacitor to filter the output voltage.

  • To ensure stability and accuracy over temperature, make sure to follow the recommended operating conditions, including the input voltage range and operating temperature range. Also, use a stable input voltage source and decouple the input voltage with a capacitor. Additionally, consider using a thermally conductive material to dissipate heat away from the device.

  • The recommended input voltage range for the REF3033AIDBZR is 4.5V to 18V. Operating the device outside of this range may affect its accuracy and stability.

  • The output voltage tolerance of the REF3033AIDBZR can be calculated by adding the initial accuracy error (±0.05% at 25°C) to the temperature coefficient error (±10ppm/°C). This will give you the total output voltage tolerance over the operating temperature range.

  • No, the REF3033AIDBZR is a voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, but it does not have the capability to regulate the output voltage. If you need a voltage regulator, consider using a separate voltage regulator IC.
