Alternate Parts for REF102BU
This table gives cross-reference parts and alternative options found for REF102BU. 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 REF102BU, 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.
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 to 22uF capacitor, and use a low-ESR output capacitor. Also, keep the PCB layout clean and avoid long traces.
The maximum current that can be drawn from the REF102BU is 10mA. Exceeding this limit may affect the accuracy and stability of the voltage reference.
The REF102BU has a temperature coefficient of 10ppm/°C, which means its output voltage will change by 10ppm for every 1°C change in temperature. This can affect the overall accuracy of the system.
Yes, the REF102BU is suitable for high-reliability and aerospace applications due to its high accuracy, low noise, and radiation-hardened design.
