S-1701W3324-U5T1G

Overview

The S-1701W3324-U5T1G is a dual-output low-dropout (LDO) voltage regulator from ABLIC's S-1701 series, housed in an SOT-89-5 surface-mount package. It provides fixed output voltages of 2.4 V and 3.3 V with a maximum continuous output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and a maximum dropout voltage of 250 mV at 100 mA load. Operating specifications include a minimum operating temperature of -40°C and a maximum of +85°C, with a power dissipation rating of 1 W.

Feature Summary

• Integrates two independent linear regulators within a single compact package to reduce board space.
• Combines voltage regulation functionality with built-in voltage detection capabilities for system monitoring.
• Maintains stable performance under varying thermal conditions across the industrial temperature range.

Applications

• Portable electronic devices requiring multiple regulated supply rails
• Embedded systems needing integrated voltage supervision
• Battery-powered equipment prioritizing low standby current consumption

Procurement Notes

Verify the specific pinout configuration against the official datasheet before integration, as package variations may exist within the series. Confirm that the required output voltages match the exact suffix codes provided by the manufacturer. Ensure thermal management strategies account for the 1 W power dissipation limit under maximum load conditions to maintain reliability.

Selection Notes

Select this component when a design requires two distinct fixed voltage outputs from a single regulator footprint. The SOT-89-5 package offers a balance between thermal performance and size for moderate current applications. Consider the 85 µA quiescent current for battery life optimization compared to higher-current alternatives.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators designed by ABLIC Inc. The series focuses on providing efficient power management solutions for portable electronics. The S-1701W3324-U5T1G specifically utilizes the W-series coding to denote its dual-output configuration within the broader product family.

Replacement Considerations

Direct substitutes within the same series include other S-1701 variants with different output voltage combinations, such as S-1701E5042-U5T1G or S-1701R1815-U5T1G, provided the electrical requirements align with the new voltage levels.
