Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix B4R against official Torex documentation to confirm the 6-USPEL package configuration, as suffixes define physical attributes rather than electrical function. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Cross-reference the part number with authorized distributors to confirm current availability and lead times before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.2V rail is required from a single-cell lithium-ion or similar power source. The 200mA output capacity suits low-to-medium power loads where size constraints are critical. Consider the 500nA quiescent current for applications prioritizing battery longevity over high-efficiency at heavy loads compared to linear regulators.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the XC9265 series of ultra-low power synchronous step-down converters. The series offers various fixed output voltages and packaging options to support diverse portable electronics designs. The A-series designation typically indicates specific performance characteristics within the broader product family, focusing on low-power operation and small form factors.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct replacements within the same series include XC9265A221MR-G (SOT-25 package) or XC9265A22B4R-G (identical specification). Verify pinout and thermal pad requirements when substituting packages. Other manufacturers' buck converters may require external components not needed here.
