Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CPR' confirms the SOT-89-5 package and fixed 3.1V output configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure compatibility with your PCB footprint design for the specified five-lead surface-mount package before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.1V output is required from a 2.5V to 5.5V input source. The 1.5A current capacity suits moderate load applications. The SOT-89-5 package offers a compact solution compared to larger alternatives. Consider the 1.2MHz switching frequency for balancing component size and efficiency requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9287 series of HiSAT-COT synchronous buck converters. The series is characterized by high integration, eliminating the need for external feedback resistors or compensation networks. Variants within the series differ primarily in output voltage settings and package types, such as USP-C-EP-6 or SOT-89-5.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct replacements must match the 3.1V fixed output, 1.5A current rating, and SOT-89-5 package. Verify that alternative parts support the same 2.5V to 5.5V input range and 1.2MHz switching frequency to maintain circuit stability and performance equivalence.
