S-1701D3026-U5T1G

Overview

The S-1701D3026-U5T1G is a low dropout voltage regulator from the ABLIC S-1701 series, featuring a dual-output configuration with fixed voltages of 2.6 V and 3.0 V. It supports a maximum output current of 400 mA per channel while maintaining a quiescent current of 85 µA. The device operates within an input voltage range of 2 V to 6.5 V and offers a typical dropout voltage of 140 mV at 100 mA. Packaged in a compact SOT-89-5 format, it ensures stable performance across a temperature range of -40°C to +85°C.

Feature Summary

• Dual-output architecture providing independent 2.6 V and 3.0 V rails
• Ultra-low quiescent current consumption for extended battery life
• Integrated overcurrent protection circuitry
• Compact surface-mount package design

Applications

• Portable consumer electronics requiring multiple voltage domains
• Battery-powered IoT sensor nodes
• Mobile communication devices
• Embedded microcontroller power systems

Procurement Notes

Verify the specific suffix U5T1G against the manufacturer's official ordering guide to confirm tape-and-reel specifications and packaging details. Ensure that the required output voltages match the fixed internal settings, as external adjustment is not supported. Cross-reference the thermal resistance data with your PCB layout requirements to maintain safe operating temperatures under full load conditions.

Selection Notes

Select this component when a single IC must supply two distinct logic levels without additional resistive dividers. The 400 mA capacity suits moderate load applications, while the 85 µA standby current benefits energy-efficient designs. Consider the SOT-89-5 footprint constraints during mechanical integration. Validate input voltage stability to ensure the dropout margin remains sufficient for both outputs simultaneously.

Part Context

This part belongs to the S-1701 series, which combines voltage regulation with detection functions in a CMOS process. The series emphasizes high accuracy and low power consumption for portable applications. The S-1701D variant specifically denotes the dual-output configuration, distinguishing it from single-output counterparts within the same product family.

Replacement Considerations

Direct substitutes include other S-1701 series parts with matching dual-output voltages and pin configurations. Verify compatibility with existing PCB footprints and thermal management strategies before swapping components.
