Procurement Notes

Verify the specific suffix MKLT against official ABLIC documentation to confirm tape-and-reel specifications and marking codes. Ensure compatibility with standard SOT-23-5 footprint requirements during PCB layout. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.6V output is required from a single-cell battery source. Consider the 25.9uA quiescent current for standby applications. Evaluate external inductor selection based on the internal switch current limits and desired ripple performance. Compare against other S-8358 variants if different output voltages or package types are needed.

Part Context

This part belongs to the S-8358 series of step-up switching regulators from ABLIC. The series is designed for low-power applications requiring high efficiency and small form factors. Variants within the series typically differ by output voltage settings and package options, sharing common control logic and protection features.

Replacement Considerations

Direct replacements include other S-8358 series parts with identical 2.6V output and SOT-23-5 packaging, such as S-8358F26MC-MKHT2U, provided pinout and electrical characteristics match exactly. Cross-series replacement requires careful verification of switching frequency and control interface compatibility.
