Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix BC1R against the official datasheet to confirm the fixed 2.15 V output setting. Ensure the LGA-8B01-8 package footprint matches your PCB design constraints. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.15 V output is required within a 5.5 V input limit. The 1.5 A current capacity suits moderate load applications. Consider the 1.2 MHz frequency for balancing efficiency and passive component size. Verify that the LGA-8B01-8 package is suitable for your assembly process.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9289 series of HiSAT-COT synchronous buck converters. The series offers various fixed output voltages determined by internal resistor networks. All members share similar electrical characteristics, including input range, current capability, and package type, differing primarily in their regulated output levels.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for other XC9289 variants with different output voltages if 2.15 V is not strictly required. Verify pin compatibility with alternative LGA-8 packages from other manufacturers if sourcing changes are necessary.
