S-1701F3430-U5T1G

Overview

The S-1701F3430-U5T1G is a specialized low-dropout regulator manufactured by ABLIC Inc., designed for battery-powered applications. It features a single fixed output voltage of 3.4V and supports an input voltage range from 2V to 6.5V. The device is housed in a compact SOT-89-5 surface-mount package, suitable for space-constrained designs. It operates within a temperature range of -40°C to +85°C and includes integrated voltage detection functionality alongside regulation capabilities.

Feature Summary

• Integrates voltage regulation with voltage detection functions for comprehensive power management
• Optimized for battery-powered devices with wide input voltage tolerance
• Compact surface-mount packaging facilitates efficient PCB layout

Applications

• Battery-powered electronic devices
• Voltage conversion circuits
• Portable consumer electronics requiring stable power supply

Procurement Notes

Verify the specific suffix U5T1G corresponds to the required reel packaging configuration. Confirm that the SOT-89-5 pinout matches your schematic requirements. Ensure the operating temperature range meets your environmental specifications. Check for any recent design status updates as some variants may be marked not for new designs.

Selection Notes

Select this component when a combined regulator and voltage detector is needed for single-output applications. The 3.4V output is fixed, so ensure compatibility with downstream loads. Consider the SOT-89-5 thermal performance if high current densities are expected. Verify input voltage stability within the 2V to 6.5V range during operation.

Part Context

This part belongs to the S-1701 series of special purpose regulators from ABLIC. These components are engineered to provide both linear regulation and voltage monitoring in a single package. The series targets portable electronics where board space and component count are critical constraints.

Replacement Considerations

Check for direct substitutes within the S-1701 family with compatible output voltages. Verify pin-to-pin compatibility with other SOT-89-5 regulators if cross-referencing. Ensure replacement parts maintain similar input voltage ranges and detection thresholds.
