S-1701D5043-U5T1G

Overview

The S-1701D5043-U5T1G is a dual-output low-dropout (LDO) voltage regulator from ABLIC's S-1701 series, housed in an SOT-23-5 package. It provides fixed outputs of 4.3 V and 5 V with a maximum output current of 400 mA. The device features a low quiescent current of 85 µA and operates within an input voltage range of 2 V to 6.5 V. It maintains a typical dropout voltage of 140 mV and a maximum of 210 mV at 100 mA. The unit supports a power dissipation of 420 mW and functions reliably between -40°C and +85°C.

Feature Summary

• Integrates two independent fixed voltage regulators in a single compact package
• Combines low quiescent current consumption with high output drive capability
• Provides stable regulation with minimal voltage drop under load conditions

Applications

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

Procurement Notes

Verify the specific suffix U5T1G corresponds to the required reel packaging quantity of 3000 units. Confirm the SOT-23-5 pinout matches your PCB footprint design. Ensure the thermal constraints allow for the specified 420 mW power dissipation in your final assembly environment.

Selection Notes

Select this component when a dual-output LDO is required to save board space. The 4.3 V and 5 V combination suits applications needing distinct logic and peripheral voltages. Consider the 85 µA standby current for battery life optimization compared to standard regulators.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. It is designed for automotive and industrial applications requiring reliable power management. The series emphasizes low power consumption and high precision in a small form factor suitable for dense circuit layouts.

Replacement Considerations

Check for other S-1701 variants with different output combinations or packages like SOT-89-5 if higher power dissipation is needed.
