S-1701W5041-U5T1G

Overview

The S-1701W5041-U5T1G is a dual-output low dropout (LDO) voltage regulator from ABLIC's S-1701 series, housed in an SOT-89-5 surface-mount package. It provides fixed positive 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 and a maximum dropout voltage of 210 mV at 100 mA load. Operating within a temperature range of -40°C to +85°C, it offers line regulation of 0.2%/V and load regulation of 40 mV, ensuring stable power delivery for sensitive electronic circuits.

Feature Summary

• Integrates two independent fixed-voltage LDO regulators within a single compact package
• Combines voltage regulation functionality with built-in voltage detection capabilities
• Maintains low power consumption through ultra-low standby current characteristics
• Ensures stable performance under varying thermal conditions across industrial temperature ranges

Applications

• Portable battery-powered consumer electronics requiring efficient dual-rail power management
• Embedded systems needing simultaneous supply for logic and peripheral components
• Industrial control modules utilizing voltage monitoring for system integrity verification
• Automotive infotainment units demanding reliable power sequencing and supervision

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and electrical tolerances. Ensure that the ordering information matches the required output voltage combination and package variant. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when dual isolated outputs are required within a constrained board area. Evaluate the input voltage headroom against the specified dropout characteristics to maintain regulation under minimum load conditions. Consider the thermal dissipation capabilities of the SOT-89-5 package relative to the expected ambient operating environment and total power loss.

Part Context

This device belongs to the S-1701 series, designed for applications combining regulation and supervision. It serves as a power management solution for systems requiring precise voltage levels alongside fault detection. The series targets space-constrained designs where multiple power rails and monitoring functions must be consolidated into minimal footprint packages.

Replacement Considerations

Consult official substitution lists for compatible variants within the S-1701 family. Verify pin-to-pin compatibility and electrical parameter alignment before replacing existing inventory.
