S-1701U3026-U5T1G

Overview

The S-1701U3026-U5T1G is a low-dropout voltage regulator from the ABLIC S-1701 series, housed in an SOT-89-5 surface-mount package. It provides two fixed positive output voltages of 2.6 V and 3 V with a maximum output current of 400 mA. The device features a typical quiescent current of 85 µA and a dropout voltage of 140 mV. It operates within a temperature range of -40°C to +85°C and includes built-in overcurrent protection and thermal shutdown circuits for enhanced reliability.

Feature Summary

• Integrates dual fixed voltage outputs (2.6 V and 3 V) in a single compact package
• Combines low-quiescent current consumption with high-output current capability
• Includes internal overcurrent protection and thermal shutdown mechanisms

Applications

• Battery-powered portable electronic devices requiring multiple voltage rails
• Embedded systems needing combined regulation and voltage detection functions
• Mobile communication modules with strict power management requirements

Procurement Notes

Verify the specific part number against official ABLIC documentation to confirm pinout configuration and electrical characteristics. Ensure compatibility with the target PCB footprint, specifically the SOT-89-5 package dimensions. Confirm that the required output voltages and current ratings meet the application's design specifications before finalizing procurement orders.

Selection Notes

Select this component when a design requires two distinct regulated voltages from a single regulator IC to save board space. It is suitable for applications where low standby current is critical alongside moderate load currents up to 400 mA. Consider the thermal performance in the SOT-89-5 package if operating near maximum current limits or elevated temperatures.

Part Context

This part belongs to the S-1701 series of combo voltage detector/regulator ICs by ABLIC. These components are designed to provide stable power supply rails while monitoring input or output voltage levels. The series targets applications demanding high integration and energy efficiency in small form factors.

Replacement Considerations

Direct substitutes include other S-1701 series variants with compatible output voltages and packages, such as S-1701E3026-U5T1G or S-1701R1815-U5T1G, provided the voltage specifications match the circuit requirements.
