Special Purpose Regulators Procurement Notes

Verify availability through authorized distributors or secondary markets, as the AS1339-BWLT is officially discontinued. Confirm that any sourced units are genuine components from ams-OSRAM USA INC. and match the original specifications. Check for potential tariff implications if shipping to the United States. Ensure compatibility with existing circuit designs before procurement.

Special Purpose Regulators Selection Notes

Select this component only for legacy designs requiring integrated PA biasing for WCDMA/NCDMA systems. Consider the obsolete status when planning long-term production. Evaluate alternative regulators if new design-in opportunities arise. Verify thermal performance within the specified -40°C to 85°C operating range for the target application environment.

Special Purpose Regulators Part Context

This part belongs to the AS1339 series of special purpose regulators developed by ams AG. These devices were engineered to simplify power management in mobile phone power amplifiers by combining switching and linear regulation technologies. The series represents a solution for efficient power delivery in wireless communication hardware.

Special Purpose Regulators Replacement Considerations

No public confirmed substitute part numbers are available. Due to the obsolete status, engineers must evaluate pin-compatible alternatives or redesign the power stage using modern multi-rail regulators suitable for current cellular standards.
