Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DPR against official datasheets to confirm the SOT-89-5 package and 3.5 V output voltage. Ensure compatibility with required thermal dissipation for the chosen enclosure. Cross-reference RoHS compliance status directly with manufacturer documentation before integration into regulated assemblies.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.5 V output is required from a 2.5 V to 5.5 V source. The SOT-89-5 package suits applications prioritizing moderate current handling in a small footprint. Consider the 1.2 MHz frequency for balancing component size and efficiency needs.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9287 series of synchronous step-down DC/DC converters. The series is characterized by high efficiency and compact design, utilizing internal NCH-NCH driver FETs. The XC9287A35DPR-G specifically offers a fixed 3.5 V output in a SOT-89-5 package, distinguishing it from other variants with different voltages or packages like USP-C-EP-6.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for XC9287A35DER-G if a USP-C-EP-6 package is preferred instead of SOT-89-5. Verify electrical equivalence for other XC9287 variants only if output voltage and current ratings match exactly.
