S-1701B3326-U5T1G

Overview

The S-1701B3326-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 2.6 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 maintains a voltage regulation accuracy of ±1%. It operates within a temperature range of -40°C to +85°C and includes integrated voltage detection functionality.

Feature Summary

• Dual independent fixed output channels providing simultaneous regulated power rails
• Integrated voltage detector for monitoring supply status without external components
• Low quiescent current consumption designed for battery-powered applications
• High output drive capability suitable for powering digital logic circuits

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-operated systems needing extended operational life
• Embedded controllers requiring integrated power management and supervision
• Industrial equipment operating in wide temperature environments

Procurement Notes

Verify the specific part number against official ABLIC documentation to confirm pinout compatibility and electrical specifications before integration. Ensure that the ordering suffix matches the required package type and tape-and-reel configuration. Cross-reference datasheet revisions to account for any potential manufacturing changes or updates to performance characteristics over time.

Selection Notes

Select this component when dual fixed outputs are required in a compact footprint. The SOT-89-5 package offers thermal efficiency for moderate current loads. Consider the 85 µA quiescent current for power-sensitive designs. Verify that the input voltage range supports the desired dropout performance at the target load current.

Part Context

This component belongs to the S-1701 series of combo voltage detectors and regulators. The series is characterized by low power consumption and high reliability. The S-1701B3326-U5T1G variant specifically combines two LDO outputs with voltage detection capabilities in a single integrated circuit solution.

Replacement Considerations

Check for direct substitutes within the S-1701 family with compatible output voltages. Verify pin-to-pin compatibility if replacing with other manufacturers' dual LDOs. Ensure equivalent thermal performance and regulatory compliance standards are met.
