S-1701U2521-M5T1G

Overview

The S-1701U2521-M5T1G is a low-dropout (LDO) voltage regulator and voltage detector combo IC from ABLIC. It features a fixed 2.5V output with a maximum input voltage range of 2V to 6.5V. The device delivers an output current of 400mA while maintaining a quiescent current of only 85µA. It operates within a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 package.

Feature Summary

• Combines LDO regulation with voltage detection functionality
• Ultra-low quiescent current for battery efficiency
• Fixed 2.5V output capability
• Compact surface-mount packaging

Applications

• Battery-powered portable devices
• Mobile communication equipment
• Consumer electronics requiring stable voltage monitoring

Procurement Notes

Verify the specific part number against official ABLIC documentation to ensure compatibility with your design requirements. Confirm that the SOT-23-5 package and electrical specifications match your system constraints before procurement. Check for any recent product change notifications or obsolescence notices directly from the manufacturer to avoid supply chain disruptions.

Selection Notes

Select this component when a combined voltage regulation and detection solution is required in a small footprint. The 85µA quiescent current makes it suitable for power-sensitive applications. Ensure the input voltage stays within the 2V to 6.5V range and that the load current does not exceed 400mA for reliable operation across the specified temperature range.

Part Context

This device belongs to the S-1701 series, which integrates LDO regulators with voltage detectors. The series is designed for applications where space is limited and power efficiency is critical. The S-1701U2521-M5T1G specifically provides a 2.5V output, distinguishing it from other variants in the family with different voltage levels.

Replacement Considerations

Consult ABLIC's official cross-reference guides for verified substitutes. Ensure any replacement maintains the same output voltage, current capacity, and package type to guarantee mechanical and electrical compatibility without redesigning the PCB layout.
