S-1701A3024-M5T1G

Overview

The S-1701A3024-M5T1G is a dual-output low-dropout (LDO) voltage regulator manufactured by ABLIC Inc., belonging to the S-1701 series. It integrates two fixed output voltages of 2.4 V and 3.0 V within a single package, designed for applications requiring multiple power rails from a single input source. The device supports a maximum output current of 400 mA per channel with a quiescent current of only 85 µA, ensuring efficient power management in battery-operated systems. It features a wide input voltage range from 2 V to 6.5 V and operates reliably across an extended temperature range of -40°C to +85°C. Packaged in a compact SOT-23-5 surface-mount format, it offers high voltage regulation accuracy of ±1% and low dropout characteristics, making it suitable for portable electronics and embedded systems.

Feature Summary

• Integrates dual fixed output channels providing simultaneous 2.4 V and 3.0 V regulation
• Ultra-low quiescent current consumption of 85 µA for enhanced energy efficiency
• High precision voltage regulation with ±1% accuracy tolerance
• Compact SOT-23-5 surface-mount package design for space-constrained applications

Applications

• Portable consumer electronics requiring multi-voltage rail generation
• Battery-powered embedded systems and IoT devices
• Mobile communication equipment and handheld terminals
• Industrial control modules needing stable low-noise power supplies

Procurement Notes

Verify the specific output voltage configuration matches the target circuit requirements before ordering, as the S-1701 series offers numerous combinations. Confirm that the SOT-23-5 package footprint aligns with the PCB layout specifications. Ensure the input voltage supply remains within the 2 V to 6.5 V operational range to maintain proper regulation. Check for any recent Product Change Notifications (PCN) from ABLIC regarding manufacturing updates or material changes. Validate thermal performance under maximum load conditions to prevent overheating in enclosed environments.

Selection Notes

Select this component when a single LDO solution is preferred over discrete regulators to save board space and simplify BOM. The 400 mA output current capability supports moderate load demands typical in microcontroller and sensor interfaces. Consider the 85 µA quiescent current for critical battery life optimization in standby modes. The wide input voltage range provides flexibility in system architecture design. Ensure adequate heat dissipation paths are planned due to the small package size and potential power dissipation at higher differential voltages.

Part Context

The S-1701A3024-M5T1G is part of ABLIC's broader S-1701 family of combo voltage detector/regulator ICs. This series is engineered to provide stable power supplies while monitoring input voltage levels, often integrating detection functions alongside regulation. The M5T1G suffix indicates the specific packaging and taping configuration for automated assembly. ABLIC specializes in analog semiconductor solutions, focusing on high-reliability power management components for automotive, industrial, and consumer markets. This particular variant exemplifies the trend toward integration and miniaturization in modern power IC design.

Replacement Considerations

Direct pin-to-pin replacements within the same S-1701 series should be evaluated based on matching output voltage pairs. Verify that alternative parts offer equivalent or superior quiescent current and dropout voltage specifications. Cross-reference package dimensions and thermal characteristics to ensure mechanical compatibility. Consult ABLIC documentation for any newer generations offering improved efficiency or additional protection features.
