S-1701D3328-U5T1G

Overview

The S-1701D3328-U5T1G is a dual-output low dropout voltage regulator manufactured by ABLIC Inc. It provides fixed output voltages of 2.8 V and 3.3 V with a maximum output current of 400 mA per channel. The device features an ultra-low quiescent current of 85 µA, ensuring efficient power management in battery-operated applications. Packaged in a compact SOT-89-5 surface-mount format, it operates within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture delivering independent fixed voltage outputs for multi-rail system requirements
• Ultra-low standby current consumption to extend operational life in portable devices
• Integrated reverse current protection circuitry to prevent backflow from output to input terminals

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered systems prioritizing extended operational duration
• Embedded circuits needing compact dual-output regulation solutions

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm exact voltage tolerances and package variants. Ensure compatibility with existing PCB footprints and thermal management strategies. Cross-reference datasheet specifications for operating temperature ranges and electrical limits before integration into final designs.

Selection Notes

Select this component when dual independent voltage rails are required within a single footprint. Consider the 400 mA output capability and 85 µA quiescent current as primary differentiators. Evaluate thermal dissipation requirements based on the SOT-89-5 package constraints and expected load conditions.

Part Context

This part belongs to the S-1701 series of low dropout regulators designed for high efficiency and low noise. It complements other ABLIC PMIC offerings by providing integrated voltage regulation with minimal external component requirements. The series targets applications demanding reliable power delivery in space-constrained environments.

Replacement Considerations

Consult official substitution lists for equivalent dual-output LDOs with matching pin configurations and electrical characteristics. Verify that alternative components support the same 400 mA output current and low quiescent current specifications.
