S-1701B3025-U5T1G

Overview

The S-1701B3025-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 positive 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 and a dropout voltage of 160 mV at 100 mA load. Operating specifications include a minimum temperature of -40 °C and a maximum of +85 °C, with a power dissipation rating of 1 W and voltage regulation accuracy of 1%.

Feature Summary

• Integrates two independent LDO regulators within a single compact package to reduce board space.
• Combines voltage regulation functionality with built-in voltage detection circuits for system monitoring.
• Maintains stable performance under varying thermal conditions across a wide industrial operating range.

Applications

• Portable electronic devices requiring multiple regulated supply rails
• Battery-powered systems utilizing integrated voltage supervision
• Embedded control units needing compact power management solutions

Procurement Notes

Verify the specific suffix U5T1G against official ABLIC documentation to confirm the exact pinout configuration and tape-and-reel packaging specifications. Ensure compatibility with the target PCB footprint for the SOT-89-5 package before finalizing procurement orders.

Selection Notes

Select this component when a design requires two distinct fixed voltage outputs from a single regulator unit. The 400 mA current capability supports moderate load requirements, while the low quiescent current aids in extending battery life for portable applications compared to higher consumption alternatives.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is characterized by its integration of linear regulation and voltage detection functions, designed to simplify power architecture in space-constrained electronics by reducing the component count required for multi-rail power distribution.

Replacement Considerations

Direct substitutes within the same series include S-1701E3026-U5T1G and S-1701W2521-U5T1G, which share identical packaging and electrical characteristics but offer different fixed output voltage combinations.
