S-1701F2522-U5T1G

Overview

The S-1701F2522-U5T1G is a low-dropout (LDO) linear voltage regulator from the ABLIC S-1701 series, featuring an integrated voltage detector. It provides a fixed positive output voltage of 2.5V with a maximum output current capability of 400mA. The device operates within an input voltage range of 2V to 6.5V and supports one output channel. It is housed in an SOT-89-5 package and is designed for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a low-dropout CMOS voltage regulator with reset function capabilities
• Provides stable fixed output voltage regulation for sensitive circuitry
• Designed for high ripple-rejection performance in power management applications

Applications

• Battery powered devices requiring efficient voltage regulation
• Converter circuits needing stable DC supply rails

Procurement Notes

Verify the specific suffix U5T1G against official ABLIC documentation to confirm pinout and thermal characteristics. Ensure compatibility with SOT-89-5 footprint requirements. Confirm RoHS compliance status through current datasheets. Validate that the 2.5V output matches system design specifications before integration.

Selection Notes

Select this component when a fixed 2.5V output at up to 400mA is required in a compact SOT-89-5 package. Consider the S-1701 series for applications demanding integrated voltage detection alongside regulation. Evaluate input voltage ranges between 2V and 6.5V against source availability. Check thermal dissipation needs for the target operating environment.

Part Context

This part belongs to the S-1701 series of high ripple-rejection LDOs from ABLIC Inc. The series is characterized by low quiescent current and integrated reset functions. The F-type designation typically indicates specific package or feature variations within the broader product line, often paired with voltage detector outputs for system protection.

Replacement Considerations

Check for direct cross-references in ABLIC's replacement guides. Verify if other S-1701 variants with different output voltages or packages meet the electrical requirements. Ensure any substitute maintains the SOT-89-5 form factor and -40°C to +85°C operating range.
