S-1701B3026-U5T1G

Overview

The S-1701B3026-U5T1G is a dual-output low-dropout (LDO) voltage regulator manufactured by ABLIC. It integrates two fixed positive output channels within a single package, providing regulated voltages of 2.6 V and 3.0 V. The device features a maximum output current of 400 mA per channel and operates with a quiescent current of 85 µA. It supports an input voltage range up to 6.5 V and functions reliably across an operating temperature range from -40 °C to +85 °C. The component utilizes a surface-mount SOT-89-5 package.

Feature Summary

• Integrates two independent fixed-voltage LDO regulators in a compact footprint
• Combines voltage regulation with built-in voltage detection functionality
• Maintains low power consumption through minimal quiescent current draw
• Provides stable output performance under varying load conditions

Applications

• Portable electronic devices requiring multiple supply rails
• Battery-powered systems needing efficient power management
• Embedded circuits utilizing combined regulation and monitoring
• Consumer electronics with space-constrained PCB layouts

Procurement Notes

Verify the specific output voltage combination matches the design requirement, as the suffix indicates 2.6 V and 3.0 V outputs. Confirm the SOT-89-5 package compatibility with the assembly process. Ensure the thermal dissipation capabilities are sufficient for the expected load current and ambient temperature conditions during operation.

Selection Notes

Select this component when a dual-rail power solution is required without consuming additional board space. The integrated voltage detector feature may eliminate the need for separate monitoring ICs. Consider the dropout voltage characteristics relative to the minimum input voltage available in the system to ensure proper regulation under all operating conditions.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. The series is designed for applications requiring both power regulation and voltage supervision. The B-series designation typically refers to specific output voltage combinations within the product line, distinguishing it from other variants with different voltage pairs or packages.

Replacement Considerations

Direct substitutes include other S-1701 series parts with identical pinouts and similar electrical characteristics but different output voltages, such as S-1701E3026-U5T1G. Verify that any replacement maintains the same package type and thermal performance requirements.
