S-1701E5040-U5T1G

Overview

The S-1701E5040-U5T1G is a low-dropout regulator from the ABLIC S-1701 series, featuring dual fixed outputs of 4.0 V and 5.0 V in an SOT-89-5 package. It delivers up to 400 mA output current with a typical quiescent current of 85 μA. The device operates within a -40°C to +85°C temperature range and includes built-in voltage detection functionality alongside regulation.

Feature Summary

• Dual-output architecture providing simultaneous regulated voltages
• Integrated voltage detection circuit for system monitoring
• Low quiescent current operation for power efficiency

Applications

• Embedded systems requiring multiple stable voltage rails
• Industrial control modules needing reliable power regulation
• Automotive electronics with strict thermal operating requirements

Procurement Notes

Verify the complete part number including suffixes against official ABLIC documentation to ensure correct output voltages and package type. Confirm that the SOT-89-5 footprint matches your PCB design constraints. Check RoHS compliance status if required by your manufacturing standards. Ensure input voltage specifications align with your system's power supply capabilities before integration.

Selection Notes

Select this component when dual independent voltage outputs are necessary from a single regulator package. The S-1701 series offers high accuracy and low dropout characteristics suitable for space-constrained designs. Consider the 400 mA current limit and thermal performance under maximum load conditions. Verify that the integrated voltage detection feature meets your system's supervision requirements without additional components.

Part Context

The S-1701 series represents ABLIC's line of low-dropout regulators combining voltage regulation with detection functions. This specific model provides two fixed output voltages optimized for applications requiring distinct power levels. The series is designed for automotive and industrial environments, offering reliability through CMOS technology and comprehensive protection features.

Replacement Considerations

Direct substitutes within the S-1701 family include models with identical output configurations and packages. Verify pin compatibility and electrical parameters before substitution. Cross-reference with ABLIC's official replacement guide for validated alternatives.
