Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix C1R against the manufacturer datasheet to confirm the fixed 1.3V output configuration. Ensure the LGA-8B01-8 package dimensions align with your PCB layout requirements. Confirm RoHS compliance status directly with the supplier documentation before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 1.3V output is required without external feedback resistors. The 1.5A current capability suits moderate load applications. Consider the 1.2MHz frequency for balancing size and noise. Verify that the 2.5V minimum input voltage meets your system's lowest battery or supply level.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9289 family of synchronous step-down DC/DC converters. The series is characterized by its integrated driver FETs and minimal external component requirements. The XC9289A13C1R-G specifically denotes the version with a fixed 1.3V output, distinguishing it from adjustable or other fixed voltage variants in the same lineup.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for XC9289A1BC1R-G (1.15V) or XC9289A1DC1R-G (1.35V) if voltage tolerance allows. Other XC9289 variants share the same package and topology but differ in output settings. Verify pin compatibility and thermal performance before substituting.
