S-1701B3430-U5T1G

Overview

The S-1701B3430-U5T1G is a CMOS low dropout voltage regulator with an integrated reset function, manufactured by ABLIC Inc. It operates within an input voltage range of 1.6 V to 5.5 V and provides a fixed output voltage of 3.0 V. The device supports a maximum output current of 400 mA while maintaining a typical quiescent current of 85 µA. It features a drop-out voltage of 290 mV at 100 mA and offers high ripple rejection. The component is housed in a compact SOT-89-5 package and is designed for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a voltage regulator with a dedicated reset function for system protection
• Delivers high ripple rejection performance suitable for noise-sensitive applications
• Maintains low power consumption through minimal quiescent current draw
• Supports stable regulation with low drop-out voltage characteristics

Applications

• Battery-powered portable electronic devices
• Voltage conversion in embedded systems
• Power management for microcontroller units

Procurement Notes

Verify the specific suffix U5T1G corresponds to the SOT-89-5 package and reel packaging configuration as documented in the official datasheet. Confirm that the 3.0 V output variant matches the design requirements. Ensure compliance with RoHS directives and check for automotive qualification status if required for the target application environment.

Selection Notes

Select this component when a combined LDO and reset signal is required in a single package. The 400 mA output capability suits moderate load applications. Consider the SOT-89-5 footprint for space-constrained designs. Verify input voltage stability remains within the 1.6 V to 5.5 V operational window to ensure proper regulation and reset threshold accuracy.

Part Context

This part belongs to the S-1701 series of high ripple-rejection low dropout CMOS voltage regulators. The series is characterized by its integration of reset functionality, making it distinct from standard LDOs. It is designed for use in consumer electronics and industrial equipment where power efficiency and system reliability are critical parameters.

Replacement Considerations

Direct substitutes include other parts within the S-1701 family with matching output voltages and package types. Cross-reference pinouts and electrical specifications carefully before substitution.
