S-1701C3326-U5T1G

Overview

The S-1701C3326-U5T1G is a specialized power management integrated circuit from ABLIC, combining a high-accuracy voltage detector with an on-chip delay circuit and a positive low-dropout (LDO) voltage regulator. It operates within an input voltage range of 2V to 6.5V and provides a fixed output of 3.3V. The device supports an output current of up to 400mA and features a quiescent current of 85µA. It is housed in a compact SOT-89-5 package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-accuracy voltage detector with an on-chip delay circuit alongside a positive LDO regulator on a single chip
• Provides low dropout voltage characteristics for efficient power regulation
• Designed specifically for battery-powered applications and converter systems

Applications

• Battery powered devices
• Converter systems
• Portable electronic equipment requiring stable voltage regulation

Procurement Notes

Verify the specific suffix U5T1G corresponds to the SOT-89-5 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the component is suitable for new designs, as some listings indicate limited availability or end-of-life status for certain variants within the S-1701 series.

Selection Notes

Select this component when a combined voltage monitoring and regulation solution is required in a small footprint. The 3.3V fixed output suits digital logic interfaces. Consider the 85µA quiescent current for battery life optimization. Verify that the 2V to 6.5V input range aligns with the source voltage profile of the target application.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators by ABLIC. The series offers various output voltages and packages, including SOT-23-5 and SOT-89-5. The C3326 designation typically indicates the 3.3V output variant within this family, designed for cost-effective and space-constrained power management tasks.

Replacement Considerations

Direct substitutes may include other parts from the S-1701 series with compatible pinouts and electrical specifications, such as the S-1701C3326-M5T1G if the SOT-23-5 package is acceptable. Cross-referencing with other manufacturers' dual-function regulator/detector ICs requires careful verification of pin compatibility and thermal performance.
