S-1701C5041-U5T1G

Overview

The S-1701C5041-U5T1G is a dual-output low dropout (LDO) voltage regulator from ABLIC's S-1701 series, housed in an SOT-89-5 package. It provides fixed output voltages of 4.1 V and 5.0 V with a maximum output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and a dropout voltage of 140 mV at rated load. 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

• Dual-output architecture providing independent regulated voltages
• Ultra-low quiescent current consumption for battery efficiency
• Integrated overcurrent protection and thermal shutdown mechanisms
• High ripple rejection capability for clean power delivery

Applications

• Portable electronic devices requiring multi-voltage rails
• Battery-powered systems prioritizing low standby power
• Embedded control units needing stable logic supply voltages
• IoT modules with strict power budget constraints

Procurement Notes

Verify the specific suffix U5T1G corresponds to the required tape-and-reel packaging configuration and quantity per manufacturer specifications. Confirm that the SOT-89-5 footprint matches the target PCB design guidelines. Ensure compliance with RoHS directives if environmental standards are mandatory for the end application. Cross-reference the exact part number against official distributor catalogs to confirm availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a dual-rail LDO solution is necessary to reduce board space and component count. The 400 mA output current supports moderate load requirements without external pass transistors. The low 85 µA quiescent current makes it suitable for applications where battery life is critical. Verify that the input voltage range accommodates the source supply while maintaining the minimum dropout requirement for both outputs under maximum load conditions.

Part Context

This part belongs to the S-1701 series of combo voltage detector/regulator ICs designed by ABLIC. The series is characterized by its combination of low power consumption and high accuracy, targeting portable electronics. The S-1701C5041-U5T1G specifically offers dual fixed outputs, distinguishing it from single-output variants within the same family. It utilizes CMOS technology to achieve low dropout performance and high ripple rejection ratios.

Replacement Considerations

Direct replacements include other S-1701 series dual-output variants such as S-1701F5043-M5T1G or S-1701E3026-U5T1G, provided the output voltage combinations match the system requirements. Ensure that the pinout and thermal characteristics of the substitute part are compatible with the existing PCB layout. Verify that the replacement maintains the same quiescent current and protection feature set.
