S-1701D5041-U5T1G

Overview

The S-1701D5041-U5T1G is a dual-output low-dropout (LDO) voltage regulator manufactured by ABLIC Inc. It provides fixed output voltages of 4.1 V and 5.0 V with a maximum continuous output current of 400 mA per channel. The device features a typical quiescent current of 85 µA, ensuring efficient power management in battery-operated applications. It operates within an input voltage range of 2 V to 6.5 V and maintains a dropout voltage of approximately 140 mV at 100 mA load. The unit offers high voltage regulation accuracy of ±1% and functions reliably across an extended temperature range from -40 °C to +85 °C.

Feature Summary

• Dual independent fixed output channels providing simultaneous voltage regulation
• Ultra-low quiescent current consumption for enhanced energy efficiency
• Integrated voltage detector functionality for system monitoring
• High precision voltage regulation with minimal dropout characteristics

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered consumer electronics with strict power constraints
• Embedded systems needing combined regulation and voltage detection
• Industrial control modules operating in extended temperature environments

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and thermal specifications. Ensure that the selected package variant matches your PCB footprint requirements. Cross-reference the manufacturing date code and lot number with quality assurance records before integration into production lines.

Selection Notes

Select this component when dual isolated outputs are required from a single LDO structure. Consider the 400 mA current limit and 140 mV dropout profile against your load transient requirements. Evaluate the 85 µA standby current impact on overall system battery life compared to higher-performance alternatives.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is designed for applications requiring both power supply stability and voltage monitoring capabilities.
