A8287SLB

Overview

The A8287SLB is a monolithic LNB supply and control voltage regulator IC designed for analog and digital satellite receivers. It features a single output configured for low noise block converter applications. The device operates within a temperature range of -40°C to +125°C and is housed in a 24-lead SOIC package.

Feature Summary

• Monolithic integration for LNB power regulation
• Optimized for analog and digital satellite receiver systems
• High thermal performance in 24-lead SOIC package

Applications

• Analog satellite receiver LNB power supplies
• Digital satellite receiver LNB control circuits
• Low noise block downconverter bias tees

Procurement Notes

Verify the specific suffix and tape-and-reel configuration against the manufacturer's current datasheet. Confirm that the 24-lead SOIC package dimensions match your PCB footprint requirements. Ensure compatibility with the target satellite receiver's voltage and current specifications before procurement.

Selection Notes

Select this component when designing power stages for satellite TV reception equipment requiring dedicated LNB regulation. It serves as a specialized solution for converting input voltages to stable levels required by low-noise block converters in both analog and digital signal processing chains.

Part Context

Allegro MicroSystems specializes in magnetic sensors and power ICs. The A8287SLB belongs to their special-purpose regulator portfolio, targeting niche communication infrastructure rather than general consumer electronics. It complements their broader suite of interface and driver solutions.

Replacement Considerations

Check for Allegro part numbers with identical pinouts and electrical characteristics. Verify if newer revisions of the A8287 series offer improved thermal handling or updated packaging options while maintaining functional equivalence for satellite receiver designs.
