A8302SETTR-T

Overview

The A8302SETTR-T is a specialized power management integrated circuit manufactured by Allegro MicroSystems, designed for converter and Low-Noise Block (LNB) applications. It functions as a dual-output voltage regulator IC housed in a 32-QFN package with exposed pad dimensions of 5x5 mm. The device operates within an input voltage range of 8.35 V to 25 V and supports an ambient operating temperature range from -20°C to +85°C. This component is classified under PMIC Specialized Voltage Regulators and is supplied in tape and reel packaging.

Feature Summary

• Dual output configuration for simultaneous LNB supply and control voltage regulation
• Integrated converter and low-noise block functionality optimized for satellite receiver systems
• Surface-mount design utilizing a compact 32-pin QFN footprint

Applications

• Satellite communication receivers
• Low-Noise Block downconverter power supplies
• Specialized voltage regulation in consumer electronics

Procurement Notes

Verify the specific suffix and package variant against the manufacturer's current datasheet before ordering. Confirm moisture sensitivity level requirements and reflow soldering profiles suitable for the 32-QFN package. Ensure the application voltage range aligns with the specified 8.35 V to 25 V input limits. Check for any recent product change notices regarding packaging or material composition updates.

Selection Notes

Select this component when a dedicated dual-output regulator is required for LNB applications within the specified voltage window. Consider the thermal performance of the 32-QFN package for the intended enclosure environment. Evaluate the need for specialized converter features versus standard linear regulators based on system efficiency requirements and noise sensitivity constraints.

Part Context

This part belongs to the A8302 series of specialized PMICs from Allegro MicroSystems. It is distinct from single-output variants like the A8300 and other series members such as the A8304. The family focuses on providing integrated solutions for satellite signal processing hardware, differentiating itself through dedicated LNB control capabilities rather than general-purpose power management.
