Alternate Parts for REF02AU
This table gives cross-reference parts and alternative options found for REF02AU. The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of REF02AU, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
REF02AU Frequently Asked Questions (FAQ)
-
The recommended output capacitor value is 10uF to 22uF, but it can be adjusted based on the specific application and noise requirements.
-
To ensure stability, make sure to decouple the input voltage with a 10uF capacitor, use a low-ESR output capacitor, and keep the output current below 10mA.
-
The temperature coefficient of the REF02AU is typically 10ppm/°C, which means the output voltage will change by 10ppm (parts per million) for every 1°C change in temperature.
-
No, the REF02AU is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, not to regulate voltage. Use a separate voltage regulator if you need to regulate voltage.
-
Keep the REF02AU away from noisy components, use a ground plane, and keep the output traces short and direct. Also, use a low-impedance output capacitor and decouple the input voltage.
