Procurement Notes

Verify the specific suffix NJLT2G against official ABLIC documentation to confirm pinout compatibility and tape-and-reel specifications. Ensure the ordering quantity aligns with manufacturer minimums. Cross-reference the RoHS compliance status directly with the latest datasheet revision to meet environmental regulatory requirements for your target market.

Selection Notes

Select this component when a fixed 5.2V output is required from a variable or lower-voltage source. The SOT-89-3 package offers a thermal advantage over smaller alternatives while maintaining a small footprint. Consider the 100kHz switching frequency for balancing electromagnetic interference and external component size requirements in dense PCB layouts.

Part Context

This part belongs to the S-8357 series of step-up switching regulators, which are engineered using CMOS technology for high withstand voltage and low current consumption. The series is characterized by its ability to operate efficiently at low input voltages, making it suitable for applications where power conservation is critical. The B52 designation specifically indicates the 5.2V output variant within this family.

Replacement Considerations

Consult official substitution lists for equivalent fixed-output boost controllers. Verify that any alternative maintains the same 5.2V output accuracy and SOT-89-3 pin configuration to ensure direct compatibility without redesigning the surrounding passive components.
