S-1701D3025-U5T1G

Overview

The S-1701D3025-U5T1G is a dual-output low dropout (LDO) voltage regulator manufactured by ABLIC Inc. It provides fixed output voltages of 2.5 V and 3.0 V with a maximum continuous output current of 400 mA per channel. The device features a typical quiescent current of 85 µA, ensuring efficient power management in battery-operated applications. It operates within an input voltage range supporting the specified outputs and maintains a maximum dropout voltage of 250 mV at 100 mA load. The regulator offers high accuracy with a voltage regulation tolerance of 1% and includes built-in protection functions such as overcurrent protection and thermal shutdown to ensure reliable operation across the industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual independent fixed output channels providing 2.5 V and 3.0 V simultaneously
• Ultra-low quiescent current consumption for extended battery life
• Integrated overcurrent and thermal shutdown protection mechanisms
• High voltage regulation accuracy with minimal dropout voltage

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered consumer electronics and IoT modules
• Embedded systems needing simultaneous logic and peripheral power supplies
• Mobile communication equipment with strict power efficiency requirements

Procurement Notes

Verify the specific part number suffix against official ABLIC documentation to confirm pinout compatibility and tape-and-reel specifications. Ensure that the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Cross-reference the date code and lot information to guarantee component authenticity and traceability. Confirm that the intended application environment falls within the specified operating temperature range and electrical limits defined in the datasheet.

Selection Notes

Select this component when a design requires two distinct regulated voltages from a single package to save board space. The 400 mA output capability supports moderate load currents for digital logic and analog peripherals. Consider the 85 µA quiescent current for applications where standby power consumption is critical. Verify that the input voltage source can maintain sufficient headroom above the highest required output voltage to prevent excessive dropout under full load conditions.

Part Context

This device belongs to the S-1701 series of dual-output LDO regulators from ABLIC. The series is characterized by low noise, high ripple rejection, and compact SOT-89-5 packaging. It complements other single-output variants in the portfolio by offering integrated dual-rail solutions for space-constrained designs. The S-1701 series is widely used in mobile and portable applications where power efficiency and reliability are paramount.

Replacement Considerations

Direct substitutes include other S-1701 series variants with different output voltage combinations, such as S-1701E3026-U5T1G or S-1701W2521-U5T1G, provided the voltage levels match the system requirements. Ensure that any replacement maintains the same SOT-89-5 footprint and pin configuration to avoid PCB redesign.
