Procurement Notes

Verify the specific suffix MLJT2G against official ABLIC documentation to confirm tape-and-reel packaging details and lead-free status. Ensure compatibility with standard SOT-23-5 footprint layouts during procurement planning. Cross-reference the part number with authorized distributors to confirm availability and authenticity before ordering.

Selection Notes

Select this model when a fixed 5.0V output is required from variable input sources between 0.9V and 5.5V. Consider the 25.9µA quiescent current for applications prioritizing battery life. Evaluate the 60mA output limit against load requirements. Compare against other S-8358 variants if different output voltages or frequencies are needed.

Part Context

This component belongs to the S-8358 series of step-up switching regulators from ABLIC. The series is characterized by high efficiency and low current consumption, suitable for single-cell lithium-ion or lithium-polymer battery applications. The S-8358F50MC variant specifically targets 5V output needs within this family.

Replacement Considerations

Direct substitutes include other S-8358 series parts with matching 5.0V output specifications, such as S-8358J50MC or S-8358Q50MC, provided pinout and functional parameters align. Verify package compatibility and electrical characteristics before substitution.
