S-1701E3327-U5T1G

Overview

The S-1701E3327-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 2.7 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 a maximum dropout voltage of 140 mV at rated load. It operates within a temperature range of -40°C to +85°C and includes built-in overcurrent protection and thermal shutdown circuits for enhanced reliability.

Feature Summary

• Dual independent fixed voltage outputs integrated into a single compact package
• Ultra-low quiescent current consumption for extended battery life in portable devices
• Integrated overcurrent protection and thermal shutdown mechanisms for robust operation

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered equipment needing efficient power management
• Embedded systems utilizing microcontrollers and memory components

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm pinout compatibility and electrical tolerances. Ensure the ordering quantity aligns with manufacturer reel specifications. Confirm RoHS compliance status through the latest product change notifications before finalizing procurement contracts.

Selection Notes

Select this component when dual voltage rails are required in space-constrained designs. Compare dropout voltage characteristics against system load requirements. Verify that the input voltage range accommodates the lowest expected supply level while maintaining regulation above the specified dropout threshold for both outputs simultaneously.

Part Context

This part belongs to the S-1701 series of dual-output LDO regulators designed by ABLIC Inc. The series targets applications demanding high efficiency and small form factors. It complements other PMIC offerings by providing simple linear regulation solutions without the complexity of switching converters.

Replacement Considerations

Check for direct cross-references within the S-1701 family sharing identical pinouts and electrical parameters. Verify package dimensions and thermal characteristics match existing board layouts before substituting.
