S-1701N2515-U5T1G

Overview

The S-1701N2515-U5T1G is a dual-output low dropout regulator from the ABLIC S-1701 series, housed in an SOT-23-5 package. It provides fixed output voltages of 1.5 V and 2.5 V with a maximum continuous output current of 400 mA per channel. The device operates within a temperature range of -40°C to +85°C and features a typical quiescent current of 85 µA. Key electrical characteristics include a maximum dropout voltage of 160 mV at 100 mA, a line regulation of 0.2%/V, and a load regulation of 40 mV. The unit supports surface mount installation and is RoHS compliant.

Feature Summary

• Dual-channel architecture delivering independent fixed voltage outputs
• Ultra-low current consumption for extended battery life
• Integrated overcurrent protection and thermal shutdown circuits
• High ripple rejection capability for stable power delivery

Applications

• Portable electronic devices requiring multi-rail power supplies
• Battery-operated systems needing efficient voltage regulation
• Embedded control units with strict power budget constraints
• Communication modules requiring stable low-noise power rails

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and tolerance levels. Ensure that the ordering quantity aligns with manufacturer reel specifications. Cross-reference the part number with the latest datasheet revision to validate environmental compliance and operational limits before integration into production designs.

Selection Notes

Select this component when a compact dual-output solution is required for space-constrained applications. The SOT-23-5 package offers a small footprint suitable for dense PCB layouts. Consider the 400 mA output capacity and low dropout characteristics for systems operating near minimum input voltage thresholds. Verify that the fixed voltage settings match the target circuit requirements without external adjustment components.

Part Context

This device belongs to the S-1701 series of dual-output LDO regulators designed by ABLIC Inc. The series emphasizes low power consumption and high accuracy, making it suitable for modern portable electronics. The S-1701N variant specifically utilizes the SOT-23-5 package, distinguishing it from other series members that may use different form factors like SOT-89-5.

Replacement Considerations

Direct substitutes within the S-1701 family include S-1701Q2515-M5T1G (SOT-23-5) and S-1701R1815-U5T1G (SOT-89-5). Verify package compatibility and pinout alignment when substituting. Ensure that the replacement part maintains the same output voltage configuration and current rating to preserve system functionality.
