Procurement Notes

Verify the specific suffix U5T1G against the manufacturer's official datasheet to confirm pin configuration and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the SOT-89-5 package. Cross-reference the part number with authorized distributors to confirm availability and authenticity, as component revisions may occur without functional changes.

Selection Notes

Select this component when a combined LDO regulator and voltage detector is required in a single package to save board space. Consider the 400 mA output current limit and 2.5 V fixed output voltage against load requirements. Evaluate the thermal performance of the SOT-89-5 package for the expected power dissipation in the application environment.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. The series is characterized by low power consumption and integrated safety functions. The S-1701U2522 variant specifically denotes the 2.5 V output version within this family, offering a solution for applications demanding precise voltage levels and system health monitoring.

Replacement Considerations

Check for direct substitutes within the S-1701 series with different output voltages or current ratings if parameter adjustments are needed. Verify pin-to-pin compatibility before considering alternative manufacturers' LDOs with integrated supervisors.

FAQ

What is the primary advantage of the S-1701U2522-U5T1G over separate regulator and detector components?

It integrates both LDO regulation and voltage detection into a single SOT-89-5 package, reducing component count and PCB area while maintaining low quiescent current.

Does the S-1701U2522-U5T1G support adjustable output voltage?

No, the '2522' designation indicates a fixed output voltage of 2.5 V. Adjustable versions exist within the S-1701 series but require different part numbers.
