S-1701U3026-M5T1G

Overview

The S-1701U3026-M5T1G is a low-dropout (LDO) voltage regulator and voltage detector combo IC from ABLIC. It features a fixed 3.0V output with a maximum output current of 400mA. The device operates within an input voltage range of 1.6V to 3.6V, maintaining a typical dropout voltage of 210mV at 400mA. It incorporates a built-in voltage detector with a reset threshold of 2.6V. The unit consumes a typical quiescent current of 85µA. It is housed in a compact SOT-23-5 package and is rated for operation between -40°C and +85°C.

Feature Summary

• Combines a low-noise LDO regulator with a voltage detector function in a single package
• Provides high output current capability of up to 400mA with low dropout voltage
• Features ultra-low quiescent current consumption for extended battery life
• Includes a dedicated voltage detection circuit with a fixed reset threshold

Applications

• Battery-powered portable electronic devices
• Mobile communication equipment
• Consumer electronics requiring stable power supply and monitoring
• Embedded systems needing combined regulation and supervision

Procurement Notes

Verify the exact suffix M5T1G corresponds to the SOT-23-5 reel packaging configuration. Confirm that the 3.0V output and 2.6V detector threshold align with system requirements. Ensure thermal management considerations are addressed for the SOT-23-5 package under maximum load conditions. Check for any specific handling or storage instructions provided by ABLIC for this component variant.

Selection Notes

Select this component when a combined regulator and voltage monitor is required in a small footprint. The 400mA output current supports moderate load demands. The 85µA quiescent current makes it suitable for battery-operated applications where power efficiency is critical. Verify that the 3.0V output level matches the target circuit voltage requirements and that the 2.6V detection threshold provides adequate margin for system stability.

Part Context

This part belongs to the S-1701 series of LDO regulators from ABLIC. The series is designed for battery-powered applications, offering low noise and low quiescent current. The S-1701U3026 variant specifically denotes the 3.0V output version. The M5T1G suffix indicates the specific tape and reel packaging format and pin configuration compatible with surface-mount assembly processes.

Replacement Considerations

Direct substitutes include other S-1701 series parts with similar electrical characteristics, such as the S-1701W3026-M5T1G or S-1701B3026-M5T1G, provided the output voltage and detector thresholds match. Ensure any replacement maintains the SOT-23-5 package and 400mA current rating. Verify compatibility with existing PCB layout and thermal design constraints.
