Procurement Notes

Verify the exact suffix MLMT2G against official ABLIC documentation to confirm tape-and-reel specifications and marking codes. Ensure compatibility with existing PCB footprints for the SOT-23-5 package. Cross-reference RoHS compliance status with the latest manufacturer declarations before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5.3V output is required from a single-cell lithium-ion or similar battery source. Consider the 25.9uA quiescent current for standby efficiency requirements. Verify that the external inductor and capacitor values meet the internal controller's operating frequency and stability criteria specified in the datasheet.

Part Context

This part belongs to the S-8358 series of step-up switching regulators from ABLIC. The series is characterized by high-efficiency CMOS technology and low power consumption. It is designed to replace linear regulators in applications where input voltage drops below the required output level, ensuring consistent performance as batteries discharge.

Replacement Considerations

Check for direct pin-compatible alternatives within the S-8358 family with different output voltages if system requirements change. Verify electrical parameters such as switching frequency and maximum duty cycle against potential substitutes to ensure circuit stability.
