S-1701A5042-M5T1G

Overview

The S-1701A5042-M5T1G is a dual-output low dropout (LDO) voltage regulator manufactured by ABLIC. It integrates two fixed output voltages of 4.2 V and 5 V within a single package. The device supports a maximum output current of 400 mA per channel with a typical quiescent current of 85 µA. It operates within an input voltage range of 2 V to 6.5 V and maintains a voltage regulation accuracy of 1%. The component is housed in an SOT-23-5 surface-mount package, suitable for space-constrained designs.

Feature Summary

• Integrates dual independent fixed voltage outputs in a compact footprint
• Features ultra-low quiescent current consumption for battery efficiency
• Provides high precision voltage regulation with 1% accuracy tolerance

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered systems prioritizing low standby power consumption
• Embedded control circuits needing precise voltage references

Procurement Notes

Verify the specific suffix M5T1G corresponds to the SOT-23-5 package configuration. Confirm that the dual output combination of 4.2 V and 5 V matches the target circuit requirements. Ensure compatibility with the specified operating temperature range during system design validation.

Selection Notes

Select this component when dual voltage rails are required from a single regulator source. The SOT-23-5 package offers a smaller footprint compared to larger alternatives. Consider the 85 µA quiescent current for applications where power conservation is critical during idle states.

Part Context

This part belongs to the S-1701 series of combo voltage detector/regulators. The series is designed for automotive and industrial applications requiring reliable power management. ABLIC manufactures these components with strict quality controls to ensure long-term stability in demanding environments.

Replacement Considerations

Check for direct substitutes within the S-1701 family sharing the same output voltages and package type. Verify pinout compatibility before replacing existing components on the PCB layout.
