S-1701C3025-M5T1G

Overview

The S-1701C3025-M5T1G is a dual-output low-dropout (LDO) voltage regulator and voltage detector manufactured by ABLIC. It provides fixed output voltages of 2.5 V and 3.0 V with a maximum output current of 400 mA per channel. The device features a low quiescent current of 85 µA, ensuring efficient power management in battery-operated applications. It operates within an input voltage range of 2 V to 6.5 V and maintains stable regulation across a temperature range of -40°C to +85°C. Packaged in a compact SOT-23-5 surface-mount format, it integrates high ripple rejection capabilities for clean power delivery.

Feature Summary

• Integrates dual linear LDO regulators with a combined voltage detection function for system monitoring.
• Delivers high output current capability of 400 mA while maintaining ultra-low standby current consumption.
• Provides precise voltage regulation with tight accuracy tolerances suitable for sensitive digital logic circuits.

Applications

• Portable electronic devices requiring extended battery life
• Mobile communication equipment and smartphones
• Embedded systems with multiple voltage domain requirements
• Battery-powered sensor modules and IoT nodes

Procurement Notes

Verify the specific suffix M5T1G corresponds to the SOT-23-5 package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain partners provide valid traceability records for quality assurance purposes. Cross-reference the full part number against the latest datasheet revision to confirm pinout compatibility with existing PCB layouts.

Selection Notes

Select this component when dual regulated outputs are required alongside voltage supervision in a minimal footprint. Compare dropout voltage specifications against the minimum input voltage available in the target application. Evaluate thermal performance constraints based on the expected load current and ambient operating conditions. Consider the 85 µA quiescent current impact on overall system efficiency during idle states compared to higher-performance alternatives.

Part Context

This model belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. The series is designed for applications demanding both power regulation and system reset functionality in a single integrated circuit. The S-1701C variant specifically denotes the dual-output configuration with fixed voltage settings, distinguishing it from single-output or adjustable variants within the broader product family.

Replacement Considerations

Direct substitutes include other S-1701 series parts with matching output voltages and package types, such as S-1701U1815-M5T1G for different voltage levels. Verify functional equivalence regarding quiescent current and dropout characteristics before substitution. Ensure that any replacement maintains the same SOT-23-5 pinout to avoid PCB redesign efforts.
