S-1701F3328-U5T1G

Overview

The S-1701F3328-U5T1G is a low dropout CMOS voltage regulator manufactured by ABLIC, featuring an integrated voltage detector. It operates within an input voltage range of 2 V to 6.5 V and provides a fixed output voltage of 3.3 V with a secondary detector threshold of 2.8 V. The device supports a maximum output current of 400 mA while maintaining a typical quiescent current consumption of 85 µA. Packaged in an SOT-23-5 configuration, it ensures stable regulation with high ripple rejection capabilities suitable for precision power management applications.

Feature Summary

• Integrates a low dropout linear regulator with a built-in voltage detection circuit
• Provides high accuracy for both regulated output and detector threshold levels
• Features low current consumption to extend battery life in portable devices

Applications

• Battery-powered portable electronic equipment requiring stable voltage rails
• Microcontroller systems needing precise power supply monitoring
• Communication modules requiring low noise and high ripple rejection

Procurement Notes

Verify the specific suffix U5T1G corresponds to the SOT-23-5 package and reel packaging configuration. Confirm that the 3.3 V output and 2.8 V detector threshold match the design requirements. Ensure compatibility with the required operating temperature range and check for any recent product change notifications from ABLIC regarding pinout or electrical characteristics before finalizing orders.

Selection Notes

Select this component when a combined LDO and voltage monitor solution is required to save board space. The 400 mA output current capability suits moderate load applications, while the 85 µA quiescent current is optimal for energy-efficient designs. Consider the SOT-23-5 footprint constraints and ensure adequate thermal dissipation for the expected power loss under maximum load conditions.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is characterized by its integration of power management and monitoring functions in a compact form factor. It utilizes CMOS technology to achieve low dropout performance and high accuracy, distinguishing it from standard single-function regulators in the ABLIC portfolio.

Replacement Considerations

Direct substitutes within the S-1701 family include variants with different output voltages or detector thresholds, such as S-1701U1815-M5T1G for lower voltage applications. Cross-family replacements require careful verification of pin compatibility, output current ratings, and package dimensions to ensure functional equivalence without redesigning the PCB layout.
