S-1701F5043-U5T1G

Overview

The S-1701F5043-U5T1G is a dual-output low dropout regulator from the ABLIC S-1701 series, housed in an SOT-23-5 package. It provides fixed output voltages of 4.3 V and 5 V with a maximum output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and operates within a temperature range of -40 °C to +85 °C. Key electrical specifications include a typical dropout voltage of 140 mV at rated load.

Feature Summary

• Integrates two independent positive linear regulators in a single compact package
• Combines voltage regulation functionality with built-in voltage detection circuits
• Maintains stable performance with ultra-low standby current consumption

Applications

• Portable electronic devices requiring multiple regulated supply rails
• Battery-powered systems utilizing voltage monitoring for power management
• Embedded control circuits needing combined regulation and detection

Procurement Notes

Verify the specific suffix U5T1G against official datasheets to confirm the SOT-23-5 package configuration and tape-and-reel shipping format. Ensure compatibility with surface-mount assembly processes. Confirm that the 4.3 V and 5 V output combination matches the target circuit design requirements before finalizing orders.

Selection Notes

Select this component when a dual-output LDO with integrated voltage detection is required in a small footprint. The S-1701 series offers high accuracy and low noise suitable for sensitive analog sections. Consider the 400 mA current capability and thermal dissipation limits in the SOT-23-5 package during PCB layout planning.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators by ABLIC. These ICs are designed to replace separate regulator and detector components, reducing board space. The series is characterized by CMOS technology, offering low power consumption and high reliability for consumer and industrial electronics.

Replacement Considerations

Check for direct pin-compatible alternatives within the S-1701 family that offer different output voltage combinations or package options such as SOT-89-5.
