S-1701D3430-U5T1G

Overview

The S-1701D3430-U5T1G is a dual-output low dropout voltage regulator from the ABLIC S-1701 series, housed in an SOT-89-5 surface-mount package. It provides fixed output voltages of 3.0 V and 3.4 V with a maximum output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and a maximum dropout voltage of 140 mV. It operates within a temperature range of -40 °C to +85 °C and includes built-in voltage detection capabilities for system monitoring.

Feature Summary

• Dual-channel fixed output configuration providing independent regulated voltages
• Ultra-low quiescent current consumption for extended battery life
• Integrated voltage detector function for input or output monitoring
• Compact SOT-89-5 package suitable for space-constrained designs

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered systems prioritizing low power consumption

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and thermal characteristics. Ensure the ordering information matches the required output voltage combination and package variant. Confirm RoHS compliance status and lead times through authorized distributors prior to final procurement decisions.

Selection Notes

Select this component when dual isolated outputs are required from a single regulator IC. Compare dropout voltage specifications against the minimum input voltage available in the target circuit. Evaluate the 400 mA current limit against peak load requirements to ensure adequate headroom and thermal performance under worst-case operating conditions.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. It shares the family's core architecture of low quiescent current operation and integrated monitoring functions. The S-1701 series is designed for applications requiring high efficiency and compact form factors in portable and industrial electronics.

Replacement Considerations

Direct substitutes include other S-1701 series variants with different output voltage combinations, such as S-1701E3026-U5T1G or S-1701R1815-U5T1G, provided the voltage levels match the design requirements. Cross-reference pinouts and thermal pads before substitution.
