S-1701Q2715-U5T1G

Overview

The S-1701Q2715-U5T1G is a low-dropout (LDO) voltage regulator and combo voltage detector IC from ABLIC. It features a single fixed output of 2.7 V with a maximum output current of 400 mA. The device operates within an input voltage range of 2 V to 6.5 V and consumes a typical quiescent current of 85 µA. It provides high accuracy with a voltage regulation tolerance of 1%. The unit is housed in a compact SOT-89-5 package, suitable for surface-mount installation.

Feature Summary

• Combines LDO regulation with voltage detection functionality
• Ultra-low quiescent current consumption for battery efficiency
• High output current capability up to 400 mA
• Fixed output voltage configuration

Applications

• Battery-powered devices
• Voltage converter circuits
• Portable electronic equipment

Procurement Notes

Verify the specific suffix U5T1G confirms the SOT-89-5 package and tape-and-reel delivery format. Confirm RoHS compliance status through official documentation. Ensure the component is designated as active or recommended for new designs, as some variants may carry 'Not For New Designs' status. Cross-reference the manufacturer part number with distributor catalogs to ensure correct pinout and electrical specifications match the application requirements.

Selection Notes

Select this component when a combined voltage regulation and detection solution is required in a small footprint. The 2.7 V fixed output suits systems needing stable power from single-cell lithium batteries. The 400 mA output current supports moderate load demands. Consider the SOT-89-5 package for thermal performance and space constraints compared to smaller SOT-23 options.

Part Context

This part belongs to the S-1701 series of special purpose regulators by ABLIC Inc. The series integrates LDO regulators with voltage detectors to simplify circuit design. The Q variant typically denotes specific package and reel configurations within the product line. These components are designed for power management in portable electronics requiring efficient voltage conversion.

Replacement Considerations

Check for direct substitutes like S-1701P2715-U5T1G or S-1701R2715-U5T1G if package differences are acceptable. Verify that alternative parts maintain the same 2.7 V output and 400 mA current rating. Ensure compatibility with existing board layout and thermal management strategies before substitution.
