Procurement Notes

Verify the specific output voltage combination and package type against your schematic requirements before ordering. Confirm that the SOT-23-5 footprint matches your PCB layout. Ensure the input voltage supply remains within the specified operational limits to maintain regulation accuracy. Check for any recent product change notices or obsolescence announcements from ABLIC regarding this part number.

Selection Notes

Select this component when dual, closely spaced voltage outputs are required from a single regulator IC. The S-1701 series is suitable for applications prioritizing low standby current alongside moderate load capabilities. Consider the thermal performance in the SOT-23-5 package if high ambient temperatures or continuous full-load operation is expected. Verify compatibility with downstream components requiring 2.0 V and 2.5 V supplies.

Part Context

This part belongs to the ABLIC S-1701 series of dual-output linear regulators. These devices are designed for general-purpose power management in compact electronic designs. The series offers various fixed output voltage combinations to suit different digital logic families. The S-1701D2520-U5T1G specifically targets applications needing simultaneous 2.0 V and 2.5 V generation with minimal external component count.

Replacement Considerations

Direct replacements within the S-1701 series include parts with identical output voltages (2.0 V/2.5 V) and the same SOT-23-5 package, such as S-1701U2520-M5T1G. Ensure substitute parts match the pinout configuration and electrical specifications exactly. Verify that any alternative packages have compatible thermal and mechanical properties.
