S-1701V3327-U5T1G

Overview

The S-1701V3327-U5T1G is a low dropout (LDO) voltage regulator with an integrated voltage detector, manufactured by ABLIC Inc. It operates within an input voltage range of 2 V to 6.5 V and provides a fixed 3.3 V output. The device supports a maximum output current of 400 mA while maintaining a typical quiescent current of 85 µA. It is housed in an SOT-89-5 package and is designed for battery-powered applications requiring stable power management.

Feature Summary

• Integrates LDO regulation with voltage detection functionality
• Supports wide input voltage range suitable for lithium-ion batteries
• Low quiescent current design for extended battery life

Applications

• Battery powered devices
• Converter circuits
• Portable electronics requiring stable 3.3V supply

Procurement Notes

Verify the specific suffix U5T1G corresponds to the SOT-89-5 package and reel packaging configuration. Confirm that the component status is acceptable for new designs, as some S-1701 variants may be marked not for new designs. Ensure compatibility with the required 3.3V output and 400mA load requirements.

Selection Notes

Select this component when a combined LDO and voltage detector solution is needed in a compact SOT-89-5 package. It is suitable for applications where input voltages vary between 2V and 6.5V, such as single-cell lithium-ion battery systems. Consider the 85µA quiescent current for efficiency-critical portable designs.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. The series offers various output voltages and packages, including SOT-23-5 and SOT-89-5. The S-1701V3327 variant specifically targets 3.3V output applications with high current capability.

Replacement Considerations

Check for direct pin-compatible alternatives within the S-1701 series with different output voltages or packages. Verify if other manufacturers offer similar combo LDO/voltage detector ICs with matching 400mA output and 2V-6.5V input range.
