Procurement Notes

Verify the specific suffix BJKT against official ABLIC documentation to confirm tape-and-reel packaging and lead-free status. Confirm that the component remains active, as availability may vary across distributors. Ensure compatibility with your PCB footprint and reflow soldering profile before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.5 V output is required without external feedback resistors. It is suitable for designs prioritizing minimal external component count and low quiescent current. Verify that the load current requirements fall within the safe operating area defined in the electrical characteristics table.

Part Context

This part belongs to the S-8520 series of DC-DC switching controllers designed for high efficiency in small form factors. The series utilizes CMOS technology to achieve low power consumption while maintaining stable regulation under varying load conditions.

Replacement Considerations

Consult the official ABLIC cross-reference guide for verified substitutes. Direct replacements must match the SOT-23-5 package and 2.5 V output specification.
