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 REF02AUE4, 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.
REF02AUE4 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 with a 0.1uF capacitor, use a low-ESR output capacitor, and keep the output current below 10mA.
-
The thermal hysteresis of the REF02AUE4 is typically around 1-2mV, which means the output voltage may vary slightly when the device is cycled through temperature changes.
-
No, the REF02AUE4 is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, not to regulate voltage.
-
To minimize noise and ripple, use a low-noise power supply, decouple the input and output with capacitors, and consider adding a noise-reducing capacitor (e.g., 10nF) between the output and ground.
