A8282SLBTR-T

Overview

The A8282SLBTR-T is a linear voltage regulator IC manufactured by Allegro MicroSystems, designed for analog and digital satellite signal receivers. It features a single output providing voltages between 12V and 20V from an input range of 16.5V to 48V. The component is housed in a 24-lead SOIC package with a wide body (7.50mm width) and operates within a temperature range of -20°C to +85°C. This device is classified as a special-purpose regulator intended for specific receiver applications.

Feature Summary

• Provides regulated output voltage suitable for satellite signal processing circuits
• Operates with high input voltage ranges up to 48V
• Integrated into a surface-mount 24-SOIC package for board integration

Applications

• Analog satellite signal receivers
• Digital satellite signal receivers

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations may exist. Confirm RoHS compliance status prior to procurement, as historical records indicate non-compliance for some variants. Check current manufacturing status, as this part number has been marked as obsolete or discontinued in several distributor databases. Ensure the specific batch matches the required humidity sensitivity level for your assembly process.

Selection Notes

Select this component only if the application requires a fixed linear regulation solution for satellite receiver systems operating within the specified 16.5V to 48V input window. Consider thermal dissipation requirements due to the linear topology when handling higher load currents. Verify that the 24-SOIC footprint aligns with existing PCB layouts, as alternative packages may not be pin-compatible.

Part Context

The A8282 belongs to the A828x series of regulators specifically engineered for satellite communication equipment. It serves as a dedicated power management solution for sensitive analog and digital front-end modules in satellite receivers. The device is distinct from general-purpose regulators due to its tailored output characteristics and robustness against the electrical noise environments typical in satellite downlink hardware.

Replacement Considerations

DigiKey lists the A8282SLB as a related variant with tube packaging instead of tape-and-reel. No direct functional equivalents are officially documented in the provided source material. Due to the obsolete status indicated in multiple sources, verify availability through authorized distributors or consider redesigning with currently active components.
