A8282SLBTR

Overview

The A8282SLBTR is a specialized integrated circuit classified as a special-purpose regulator, manufactured by Allegro MicroSystems. It functions as a converter for analog and digital satellite signal receivers. The device features a single output with a voltage range of 12V to 20V, operating from an input supply between 16.5V and 48V. It is housed in a 24-SOIC surface-mount package (7.50mm width) and supports an operating temperature range of -20°C to 85°C. The component is currently listed as obsolete.

Feature Summary

• Designed specifically for use in analog and digital satellite signal receiver applications
• Provides regulated power conversion within a defined input and output voltage window
• Utilizes a 24-pin SOIC surface-mount package for board integration

Applications

• Analog satellite signal receivers
• Digital satellite signal receivers
• Satellite communication terminal power systems

Procurement Notes

Verify component obsolescence status prior to design finalization, as the A8282SLBTR is marked as discontinued. Confirm that the 24-SOIC footprint matches existing PCB layouts. Check for RoHS compliance requirements against the non-compliant status indicated in distributor records. Ensure input voltage ranges align with system power rails before procurement planning.

Selection Notes

Select this component only for legacy designs requiring specific satellite receiver regulation. Evaluate the 16.5V to 48V input range against available supply voltages. Consider the 12V to 20V output capability for downstream load requirements. Assess thermal performance within the -20°C to 85°C operational envelope. Review pinout compatibility if replacing older variants in the A828x series.

Part Context

The A8282SLBTR belongs to the A8282 family of regulators from Allegro MicroSystems. It shares functional similarities with other parts in the A8281-82 series, such as the A8281SLB, which targets similar satellite reception applications. These components are distinct from general-purpose PMICs, focusing on niche converter roles for broadcast equipment.

Replacement Considerations

Public data indicates the A8282SLB is obsolete. No direct substitute part numbers are confirmed in the provided source material. Designers should consult manufacturer documentation for potential cross-references or newer generation alternatives.
