Procurement Notes

Verify the specific suffix U5T1G against official ABLIC documentation to confirm the exact pin configuration and electrical tolerances. Ensure compatibility with the target PCB footprint for the SOT-89-5 package. Confirm that the 2.5 V output aligns with the load requirements. Check for any recent Product Change Notifications (PCN) affecting manufacturing or specifications before finalizing procurement orders.

Selection Notes

Select this component when a single IC solution is required for both voltage regulation and voltage detection in space-constrained designs. The SOT-89-5 package offers a balance between thermal performance and board area efficiency. Consider the 85 uA quiescent current impact on overall battery life compared to higher-current alternatives. Verify input voltage ranges to ensure sufficient headroom for the specified 400 mA output current under all operating conditions.

Part Context

This part belongs to the S-1701 series of high ripple-rejection low dropout CMOS voltage regulators from ABLIC. The series is characterized by its combination of power regulation and voltage detection functions, targeting efficiency in mobile and battery-operated systems. The U5T1G suffix denotes the specific output voltage, package type, and tape/reel packaging format defined by the manufacturer.

Replacement Considerations

Direct substitutes include other parts within the S-1701 family sharing the same SOT-89-5 package and 2.5 V output, such as variants with different current ratings if load requirements change. Cross-reference with similar LDOs featuring integrated reset functions from other manufacturers, ensuring pin-out compatibility and equivalent electrical parameters are maintained.
