Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm package integrity and RoHS compliance upon receipt. Cross-reference datasheet revisions to ensure compatibility with design requirements. Validate part markings against official documentation to prevent counterfeit risks during procurement.

Selection Notes

Select this component when precise voltage referencing is required with tight tolerance and low drift over temperature. Consider the 8-SOIC package for surface-mount assembly constraints. Evaluate the 15 mA source current capability against load demands. Ensure input voltage remains within the specified operational range for optimal regulation performance.

Part Context

This device belongs to the MAX6133 series of high-precision, low-power voltage references. It is designed for portable and communication applications where tiny packaging and excellent precision are critical. The series integrates bandgap technology to achieve low noise and high stability, distinguishing it from standard shunt references by saving system power and minimizing external components.

Replacement Considerations

Check for pin-compatible alternatives within the same family offering different output voltages or packages. Verify if upgraded series members provide improved temperature coefficients or noise specifications while maintaining the SOIC-8 footprint.
