S-1701W3328-U5T1G

Overview

The ABLIC S-1701W3328-U5T1G is a dual-output low-dropout (LDO) voltage regulator from the S-1701 series, manufactured by ABLIC Inc. It provides fixed output voltages of 2.8 V and 3.3 V with a maximum continuous output current of 400 mA per channel. The device features an ultra-low quiescent current of 85 µA and operates within an input voltage range of 1.8 V to 6.5 V. It utilizes an SOT-89-5 surface-mount package and maintains a typical dropout voltage of 160 mV at 100 mA load. The unit supports a junction temperature range from -40°C to +85°C and offers a line regulation of 0.2%/V.

Feature Summary

• Integrates two independent LDO regulators with a combined voltage detector function in a single compact package.
• Achieves ultra-low power consumption through an 85 µA quiescent current specification for battery-operated applications.
• Provides stable regulation with a low dropout voltage of 160 mV at 100 mA load current.
• Ensures high precision with a voltage adjustment accuracy of ±1%.

Applications

• Portable electronic devices requiring efficient multi-rail power management
• Battery-powered systems utilizing voltage detection for power monitoring
• Embedded circuits needing isolated regulated supplies for logic and peripherals

Procurement Notes

Verify the specific suffix U5T1G against official ABLIC documentation to confirm the exact pinout configuration and tape-and-reel specifications. Ensure the ordering quantity aligns with manufacturer minimum order requirements. Cross-reference the datasheet revision date to validate thermal characteristics and electrical limits before finalizing procurement contracts.

Selection Notes

Select this component when dual fixed outputs are required without external resistors. Compare the 160 mV dropout voltage against system headroom requirements. Evaluate the 400 mA current limit against peak load demands. Consider the SOT-89-5 package size constraints relative to PCB layout limitations.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. It shares the core architecture with variants like S-1701W2521-U5T1G but differs in output voltage settings. The series is designed for low-power portable electronics, offering a balance between efficiency and integration density compared to discrete solutions.

Replacement Considerations

Direct substitutes include other S-1701 series parts with compatible packages and current ratings, such as S-1701W2521-U5T1G or S-1701E3026-U5T1G, provided the output voltage requirements match the application design.
