Procurement Notes
Verify the specific suffix configuration against official MaxLinear documentation to ensure compatibility with required packaging and environmental specifications. Confirm availability status as distribution channels may vary due to product lifecycle changes. Validate RoHS compliance details directly with the manufacturer or authorized distributors before procurement integration.
Selection Notes
Select this component when a stable, adjustable reference voltage is required in space-constrained designs utilizing SOT-23-3 packages. Ensure the application circuit can maintain the minimum shunt current of 400 uA for proper regulation. Verify that the operating temperature environment falls within the specified 0°C to +105°C range for optimal performance.
Part Context
This part belongs to the SPX2431 series of precision shunt regulators produced by MaxLinear. It serves as a two-terminal voltage reference alternative to fixed-bandgap devices, offering flexibility in system design through external resistor programming. The series is categorized under PMIC voltage references for power management applications.
Replacement Considerations
Consult official MaxLinear substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully when evaluating potential replacements from other manufacturers.
