S-1701C5041-M5T1G

Overview

The S-1701C5041-M5T1G is a low-dropout (LDO) voltage regulator and voltage detector combo IC from the ABLIC S-1701 series. It features a fixed output voltage of 4.1 V with a maximum output current of 400 mA. The device operates within an input voltage range of 2 V to 6.5 V and maintains a typical dropout voltage of 140 mV at 100 mA. It incorporates a built-in voltage detector that triggers when the input voltage falls below a specific threshold, typically set near the regulated output level. The IC consumes a low quiescent current of 85 µA, ensuring efficient power management in battery-operated applications.

Feature Summary

• Integrates a fixed-output LDO regulator with a dedicated voltage detection function for system monitoring.
• Provides high output current capability up to 400 mA while maintaining low quiescent current consumption.
• Features a compact SOT-23-5 surface-mount package suitable for space-constrained designs.

Applications

• Battery-powered portable electronics requiring stable voltage regulation and low standby current.
• Microcontroller systems needing integrated brown-out detection or reset signal generation.
• Communication modules requiring reliable power supply monitoring under varying load conditions.

Procurement Notes

Verify the exact output voltage and detector threshold specifications against the official ABLIC datasheet for part number S-1701C5041-M5T1G before integration. Confirm RoHS compliance status and ensure the SOT-23-5 footprint matches your PCB layout requirements. Check for any recent Product Change Notifications (PCNs) that may affect pinout or electrical characteristics.

Selection Notes

Select this component when a combined regulator and voltage monitor solution is required to reduce bill-of-materials count. Ensure the input voltage remains above the minimum operating level while staying within the absolute maximum rating. Consider thermal dissipation if the load current approaches the 400 mA limit, as power loss depends on the input-output voltage differential.

Part Context

This part belongs to the S-1701 series of combo LDO regulators and voltage detectors by ABLIC Inc. The series is designed for applications demanding both power regulation and system supervision in a single small package. Variants within the series differ primarily in their fixed output voltage levels and detector thresholds, allowing customization for various logic families and battery chemistries.

Replacement Considerations

Direct substitutes must match the SOT-23-5 package, 400 mA output current, and similar quiescent current specs. Verify that alternative parts offer comparable dropout voltage and include an integrated voltage detector function. Cross-reference pinouts carefully to ensure compatibility without circuit redesign.
