Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot codes against official documentation. Ensure storage conditions align with moisture sensitivity levels defined in the datasheet. Cross-reference ordering information with the latest product specifications to avoid discrepancies in suffix designations.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 2.75 V output is required within the 2.5-5.5 V input range. Consider the 1.5 A current capability and 1.2 MHz frequency for space-constrained designs. Evaluate thermal performance requirements given the SOT-89-5 package size and operating temperature range relative to ambient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9288 series of synchronous buck converters. Variants differ primarily by fixed output voltage settings, indicated by alphanumeric codes in the part number. All models share common electrical characteristics such as input range, switching frequency, and package type, differing only in their regulated output level.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Other XC9288 variants with different output voltages may serve as functional substitutes if voltage requirements change. Direct replacements must maintain identical input/output specifications and pin compatibility. Verify that alternative parts support the same HiSAT-COT architecture and control modes.
