A8304SESTR-T

Overview

The A8304SESTR-T is a specialized single LNB supply and control voltage regulator manufactured by Allegro MicroSystems. It operates within an input voltage range of 10 V to 16 V and provides an adjustable output voltage between 13.3 V and 19.7 V. The device is housed in a 16-WFQFN package with dimensions of 3x3 mm and features exposed pads for thermal management. It supports surface mount installation and functions reliably across a temperature range of -20°C to +85°C, drawing a typical operating supply current of 15 mA.

Feature Summary

• Provides dedicated power regulation specifically designed for Low Noise Block downconverter (LNB) applications
• Integrates control logic for managing LNB supply states and switching requirements
• Utilizes a compact 16-pin QFN footprint to minimize printed circuit board area consumption

Applications

• Satellite television receiver systems
• Digital satellite signal reception equipment
• LNB power supply modules

Procurement Notes

Verify the exact part number suffix against official manufacturer documentation to confirm package type and tape specifications. Ensure compatibility with existing PCB footprints, as the component utilizes a 16-WFQFN package with exposed thermal pads. Confirm moisture sensitivity level handling procedures during assembly to prevent damage. Cross-reference ordering information with authorized distributors to ensure authenticity and traceability of the semiconductor unit.

Selection Notes

Select this component when designing circuits requiring precise voltage regulation for satellite signal processing hardware. The device is suitable for systems needing stable power delivery to LNB units within the specified input window. Consider the thermal performance of the QFN package and ensure adequate copper pour for heat dissipation. Verify that the required output voltage range aligns with the specific LNB operational parameters of the target application design.
