S-1701W5042-M5T1G

Overview

The S-1701W5042-M5T1G is a dual-output low dropout voltage regulator manufactured by ABLIC. 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. It operates within a temperature range of -40°C to +85°C and utilizes an SOT-23-5 surface-mount package. Key electrical specifications include a line regulation of 0.2%/V, load regulation of 40 mV, and a power dissipation rating of 1 W.

Feature Summary

• Integrates dual fixed voltage outputs for combined regulation and detection applications
• Maintains ultra-low standby current consumption suitable for battery-powered systems
• Provides stable voltage regulation with high accuracy across the operating temperature range

Applications

• Portable electronic devices requiring efficient power management
• Battery-operated equipment needing extended operational life
• Embedded systems utilizing multiple voltage rails from a single source

Procurement Notes

Verify the specific suffix M5T1G corresponds to the SOT-23-5 package and reel packaging configuration. Confirm that the 4.2 V and 5 V output combination matches the design requirements. Ensure compliance with RoHS standards and check for any recent product change notifications affecting this part number before finalizing procurement orders.

Selection Notes

Select this component when dual independent voltage rails are required in a compact footprint. The 400 mA output capability supports moderate load currents. Consider the 85 µA quiescent current for energy-sensitive designs. Verify input voltage ranges exceed the higher output voltage to ensure proper dropout performance under all load conditions.

Part Context

This part belongs to the S-1701 series of combo voltage detector/regulators from ABLIC. These ICs combine linear regulation with voltage monitoring functions. The series offers various output voltage combinations and packages to suit different application constraints while maintaining consistent low-power characteristics and reliability standards.

Replacement Considerations

Direct substitutes within the S-1701 series include parts with identical output voltages and package types. Verify pin compatibility and thermal characteristics when replacing. Cross-reference with other ABLIC LDO families if package or current ratings differ.
