S-1701A3327-U5T1G

Overview

The S-1701A3327-U5T1G is a dual-output low dropout (LDO) voltage regulator and voltage detector manufactured by ABLIC. It provides fixed output voltages of 2.7 V and 3.3 V with a maximum output current of 400 mA per channel. The device features a typical quiescent current of 85 µA, ensuring efficient power management in battery-operated applications. It operates within an input voltage range of 2 V to 6.5 V and maintains a voltage regulation accuracy of 1%. The component is housed in a compact SOT-89-5 surface-mount package, suitable for space-constrained designs requiring stable dual-rail power supplies.

Feature Summary

• Integrates dual LDO regulators with a combined voltage detection function for system monitoring
• Maintains high efficiency through ultra-low quiescent current consumption during operation
• Delivers stable regulated outputs with tight voltage accuracy specifications under varying load conditions

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered systems needing extended operational life through low standby current
• Embedded controllers requiring integrated voltage supervision for reset generation

Procurement Notes

Verify the specific output voltage combination of 2.7 V and 3.3 V against your schematic requirements before ordering. Confirm that the SOT-89-5 package dimensions align with your PCB footprint constraints. Ensure the input voltage supply remains within the specified 2 V to 6.5 V range to guarantee proper regulation and prevent damage to the internal circuitry.

Selection Notes

Select this component when a single IC solution is needed to provide two distinct fixed voltages alongside voltage monitoring capabilities. It is appropriate for designs where board space is limited and minimizing component count is a priority. Consider the thermal performance of the SOT-89-5 package if high ambient temperatures or significant power dissipation are expected in the application environment.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. The series is designed to replace discrete regulator and detector components, simplifying circuit design. The suffix U5T1G indicates the specific package type and tape-and-reel packaging configuration used for automated assembly processes.

Replacement Considerations

Direct substitutes include other parts from the S-1701 family with matching output voltages, such as S-1701N3327-U5T1G or similar variants. Verify pin compatibility and thermal characteristics when cross-referencing with competitors' dual-output LDOs.
