S-1701R3430-M5T1U

Overview

The S-1701R3430-M5T1U is a specialized low-dropout voltage regulator manufactured by ABLIC Inc., designed for battery-powered applications. It operates within an input voltage range of 1.5 V to 5.5 V and provides a fixed output voltage of 3.0 V with a maximum output current of 100 mA. The device features a typical dropout voltage of 18 mV at 100 mA, ensuring efficient power management even when the input voltage approaches the output level. Packaged in a compact SOT-23-5 surface-mount format, it supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrated conversion function optimized for battery voltage regulation
• Ultra-low dropout performance for extended battery life
• Compact SOT-23-5 package suitable for space-constrained designs

Applications

• Battery-powered portable electronic devices
• Mobile communication equipment
• Consumer electronics requiring stable 3.0 V supply

Procurement Notes

Verify the specific suffix M5T1U against official ABLIC documentation to confirm pinout and marking details. Ensure compatibility with your PCB footprint and thermal requirements. Cross-reference the datasheet revision date to validate electrical characteristics. Confirm RoHS compliance status through manufacturer declarations before integration into production.

Selection Notes

Select this component when a fixed 3.0 V output is required from varying battery sources between 1.5 V and 5.5 V. Its low dropout characteristic makes it suitable for applications where input voltage may sag near the output level. The SOT-23-5 package offers a balance of current capacity and board space efficiency for general-purpose PMIC needs.

Part Context

This part belongs to the S-1701 series of low-dropout regulators from ABLIC, which are engineered for high efficiency in portable devices. The series typically includes variants with different output voltages and current ratings, all sharing common architectural benefits such as low quiescent current and robust thermal protection mechanisms for reliable operation.

Replacement Considerations

Consult ABLIC's official substitution guide for direct replacements. Verify that alternative LDOs match the 3.0 V output, 100 mA current capability, and SOT-23-5 package dimensions. Ensure equivalent dropout voltage and operating temperature range specifications.
