S-1701Q3315-U5T1G

Overview

The S-1701Q3315-U5T1G is a dual-output low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, housed in an SOT-89-5 surface-mount package. It provides fixed output voltages of 1.5 V and 3.3 V with a maximum continuous output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and operates within an input voltage range supporting these outputs. It functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Dual independent output channels providing simultaneous 1.5 V and 3.3 V regulation
• Ultra-low quiescent current consumption for enhanced power efficiency
• Integrated voltage detection functionality combined with linear regulation
• High ripple rejection capability for stable noise-sensitive applications

Applications

• Portable electronic devices requiring multiple regulated supply rails
• Battery-powered systems prioritizing low standby current
• Embedded circuits needing precise voltage references
• Industrial control modules operating in wide temperature environments

Procurement Notes

Verify the specific suffix U5T1G confirms the SOT-89-5 package and reel packaging format. Confirm RoHS compliance status through official manufacturer documentation or certified datasheets before integration. Ensure input voltage constraints align with the 1.5 V and 3.3 V output requirements to maintain proper dropout margins during operation.

Selection Notes

Select this component when dual fixed outputs are required without external resistors. Compare dropout voltage specifications against load conditions to ensure regulation stability. Evaluate thermal performance based on total power dissipation across both channels. Verify that the 400 mA current rating meets peak load demands for both the 1.5 V and 3.3 V rails simultaneously.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators designed by ABLIC Inc. The series emphasizes low power consumption and high accuracy for portable applications. The S-1701Q variant specifically denotes the dual-output configuration with fixed voltage settings, distinguishing it from single-output or adjustable variants within the same family.

Replacement Considerations

Direct substitutes include other S-1701 series parts with identical pinouts and dual-output configurations, such as S-1701R1815-U5T1G or S-1701E3026-U5T1G, provided the output voltage requirements match the application needs. Verify package compatibility and electrical parameters before substitution.
