S-1701U5042-M5T1G

Overview

The S-1701U5042-M5T1G is a dual-output low dropout (LDO) voltage regulator from the ABLIC S-1701 series, designed for automotive applications. It provides fixed output voltages of 4.2 V and 5 V with a maximum output current of 400 mA per channel. The device features an ultra-low quiescent current of 85 µA and operates within an input voltage range of 2 V to 6.5 V. It utilizes an SOT-23-5 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates two independent fixed-voltage LDO regulators in a single compact package
• Combines voltage regulation with built-in voltage detection capabilities
• Optimized for low power consumption with minimal quiescent current draw

Applications

• Automotive electronic control units (ECUs)
• Infotainment system power distribution
• Sensor module power supply
• Body control modules

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and thermal characteristics. Ensure that the selected variant meets the required automotive qualification standards for your target application environment. Cross-reference datasheet specifications for dropout voltage and load regulation before finalizing the design.

Selection Notes

Select this component when dual isolated outputs are required from a single power rail in space-constrained automotive designs. The SOT-23-5 package offers a balance between thermal performance and footprint size. Consider the 400 mA current rating and 85 µA standby current as key differentiators for battery-sensitive systems requiring efficient power management.

Part Context

This part belongs to the ABLIC S-1701 series of automotive-grade linear regulators. The series is characterized by its combination of voltage regulation and detection functions, targeting safety-critical and general automotive electronics. The M5T1G suffix indicates the specific package type and tape-and-reel packaging configuration used for automated assembly.

Replacement Considerations

Direct replacements include other S-1701 series variants with compatible output voltages and packages, such as S-1701D5043-M5T1G or S-1701V5040-M5T1G, provided the output voltage levels match the circuit requirements.
