Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and functional compatibility. Ensure the ordering quantity aligns with manufacturer reel specifications. Confirm RoHS compliance status through the latest datasheet before integration into production designs.

Selection Notes

Select this component when dual fixed outputs near 1.5 V are required in a compact surface-mount package. Compare dropout voltage and thermal dissipation limits against the target application's load profile. Verify that the input voltage range accommodates the lowest expected supply level while maintaining regulation.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators by ABLIC Inc. The series is designed for portable equipment, offering low current consumption and small package options. The M5T1G suffix indicates the SOT-23-5 packaging configuration used for space-constrained designs.

Replacement Considerations

Check for direct substitutes within the S-1701 family sharing the same output voltages and package type. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
