S-1701F5040-U5T1G

Overview

The S-1701F5040-U5T1G is a dual-output low dropout (LDO) voltage regulator from the ABLIC S-1701 series, housed in an SOT-23-5 package. It provides fixed output voltages of 4.0 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 of 2 V to 6.5 V. It maintains a maximum dropout voltage of 210 mV at 100 mA load. The component supports a junction 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 4.0 V and 5.0 V rails
• Integrated voltage detection function combined with regulation
• Built-in overcurrent protection and thermal shutdown circuits
• Low quiescent current consumption for power efficiency

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered systems needing efficient power management

• Industrial control modules operating in extended temperature ranges

Procurement Notes

Verify the specific suffix U5T1G corresponds to the SOT-23-5 package and reel packaging configuration. Confirm that the 4.0 V and 5.0 V output combination matches the design requirements. Ensure compatibility with the required input voltage range and load conditions. Check for RoHS compliance documentation if environmental regulations apply. Validate the manufacturer part number against official ABLIC catalogs to avoid counterfeit components.

Selection Notes

Select this component when dual regulated outputs are needed from a single IC footprint. The S-1701 series offers high accuracy and low noise suitable for sensitive analog circuits. Consider the thermal performance in the SOT-23-5 package under maximum load conditions. Verify that the 400 mA current rating meets the peak demand of both output channels simultaneously. Evaluate the dropout voltage characteristics relative to the minimum available input voltage.

Part Context

This device belongs to the ABLIC S-1701 series of LDO regulators, which integrate voltage detection functions. The series is designed for applications requiring compact solutions with multiple voltage rails. The S-1701F variant specifically utilizes the SOT-23-5 package, offering a balance between current capability and board space. The integration of detection logic allows for simplified system monitoring without additional discrete components.
