S-1701A3430-U5T1G

Overview

The S-1701A3430-U5T1G is a dual-output low-dropout (LDO) voltage regulator manufactured by ABLIC Inc. It integrates two fixed output voltages of 3.0 V and 4.0 V within a single package. The device supports a maximum output current of 400 mA per channel with a typical quiescent current of 85 µA. It features a dropout voltage of approximately 260 mV at 100 mA load. The component operates within an input voltage range up to 6.5 V and provides a voltage regulation accuracy of ±1%. It is housed in a compact SOT-89-5 surface-mount package suitable for space-constrained designs.

Feature Summary

• Dual independent fixed output channels providing simultaneous 3.0 V and 4.0 V rails
• Ultra-low standby current consumption for extended battery life in portable devices
• Integrated voltage detector function for system monitoring and reset control
• High ripple rejection ratio ensuring stable power delivery under noisy conditions

Applications

• Portable electronic devices requiring multiple regulated supply rails
• Battery-powered systems needing efficient power management
• Embedded controllers requiring integrated voltage supervision
• Communication modules with strict power consumption limits

Procurement Notes

Verify the specific suffix U5T1G corresponds to the required tape and reel packaging quantity of 1000 units. Confirm that the SOT-89-5 pinout matches your PCB footprint design. Ensure the operating temperature range meets your application requirements. Check for any recent product change notifications affecting electrical characteristics or manufacturing location.

Selection Notes

Select this component when dual isolated outputs are needed from a single LDO structure. The 400 mA current capability suits moderate load applications. Consider the 85 µA quiescent current for battery-operated efficiency. Verify input voltage headroom against the specified dropout voltage at maximum load. Compare thermal dissipation capabilities within the SOT-89-5 package for your specific ambient conditions.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is characterized by low quiescent current and high precision. Other variants in the family offer different output voltage combinations and packages such as SOT-23-5. The S-1701 series targets applications requiring compact power solutions with integrated monitoring functions.

Replacement Considerations

Direct substitutes include other S-1701 series parts with matching output voltages and package types. Verify pin compatibility before substitution. Cross-reference with similar dual-output LDOs if exact voltage matches are unavailable. Ensure replacement parts maintain the same quiescent current and regulatory accuracy specifications.
