S-1701A3430-U5T1U

Overview

The S-1701A3430-U5T1U is a CMOS-based low dropout voltage regulator from the S-1701 series, manufactured by ABLIC Inc. It integrates a high-accuracy voltage detector and a reset function within a single chip. The device provides a fixed output voltage of 3.3 V with a maximum output current capability of 400 mA. It operates within an input voltage range supporting this regulation and features a typical quiescent current of 85 µA. The component is housed in a compact SOT-89-5 surface-mount package, suitable for space-constrained designs requiring combined power management and system supervision.

Feature Summary

• Utilizes CMOS technology to achieve ultra-low quiescent current consumption
• Provides stable fixed output voltage regulation with high ripple rejection
• Designed for battery-powered applications requiring efficient power management

Applications

• Battery powered devices
• Converter circuits
• Portable electronic equipment

Procurement Notes

Verify the specific suffix U5T1U against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the SOT-89-5 configuration. Cross-reference the part number with official ABLIC distributors to confirm availability and authenticity. Check for any recent design status updates, as some variants may be marked as not for new designs.

Selection Notes

Select this component when a combined LDO regulator and voltage supervisor is required to minimize board space. The 400 mA output current supports moderate load requirements while maintaining low power consumption. The fixed 3.3 V output simplifies design for standard logic levels. Consider the thermal performance of the SOT-89-5 package under maximum load conditions and ambient temperature variations.
