A8300SESTR-T-1

Overview

The A8300SESTR-T-1 is a specialized integrated circuit designed for Low Noise Block (LNB) converter voltage regulation. Manufactured by Allegro MicroSystems, it operates within an input voltage range of 10 V to 16 V and provides a single regulated output. The device is housed in a 24-WFQFN package with exposed pad, measuring 4x4 mm. It supports surface mount installation and functions reliably across an ambient temperature range of -20°C to +85°C.

Feature Summary

• Dedicated LNB converter voltage regulation
• Single output configuration
• Surface mount QFN packaging

Applications

• Satellite receiver systems
• LNB power supply units
• Satellite communication equipment

Procurement Notes

Verify component status as the A8300SESTR-T-1 is listed as obsolete or end-of-life. Confirm availability of alternative sources or suitable replacement parts from the manufacturer's current portfolio before finalizing procurement plans. Ensure compliance with RoHS3 specifications if required by the target application.

Selection Notes

Select this component only if legacy compatibility with existing A8300 series designs is mandatory. Evaluate current Allegro MicroSystems alternatives such as the A8304SESTR-T for new designs, as it offers similar LNB regulation capabilities in a different package format while maintaining active production status.

Part Context

This part belongs to the A8300 series of specialized PMICs focused on satellite signal processing power management. It serves as a dedicated regulator for powering and controlling LNB components in direct broadcast satellite receivers. The series is characterized by high integration and low noise performance suitable for sensitive RF applications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider evaluating the A8304SESTR-T for functional equivalence in LNB applications, though package differences exist.
