S-1701U5041-U5T1G

Overview

The S-1701U5041-U5T1G is a dual-output low dropout (LDO) voltage regulator from the ABLIC S-1701 series. 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 operates within an input voltage range up to 6.5 V. It utilizes a SOT-23-5 surface-mount package and maintains a typical dropout voltage of 140 mV at rated load. The unit supports an operating temperature range from -40 °C to +85 °C and includes built-in overcurrent protection and thermal shutdown circuits for system reliability.

Feature Summary

• Dual independent fixed output channels providing simultaneous voltage regulation
• Ultra-low quiescent current consumption for extended battery life in portable applications
• Integrated overcurrent protection and thermal shutdown mechanisms for enhanced safety

Applications

• Battery-powered portable electronic devices requiring multiple stable voltage rails
• Mobile communication equipment and handheld terminals
• Embedded systems utilizing CMOS technology for power management

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and electrical tolerances. Ensure that the ordering specifications match the required output voltage combination and package type. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when dual isolated outputs are required from a single regulator IC to save board space. The S-1701U5041-U5T1G is suitable for designs needing high accuracy and low noise. Consider the thermal dissipation capabilities of the SOT-23-5 package relative to the expected load current and ambient temperature conditions during the design phase.

Part Context

This part belongs to the S-1701 series of positive LDO regulators developed using CMOS technology by ABLIC Inc. The series is characterized by high ripple rejection ratios and low current consumption. The S-1701U5041-U5T1G specifically offers dual outputs, distinguishing it from single-output variants within the same family while sharing common protection features and packaging standards.

Replacement Considerations

Direct substitutes include other S-1701 series parts with identical dual-output voltage configurations and SOT-23-5 packaging. Verify functional equivalence regarding dropout voltage and current limits before substitution.
