S-1701E3430-M5T1G

Overview

The S-1701E3430-M5T1G is a low-dropout (LDO) voltage regulator manufactured by ABLIC Inc., belonging to the S-1701 series. It integrates a voltage detector function within a compact package. The device provides two fixed output voltages: 3.0 V and 4.3 V. It supports a maximum output current of 400 mA with a typical quiescent current of 85 µA. The component operates within an input voltage range of 2 V to 6.5 V and features a dropout voltage of 140 mV at specified loads. It is housed in a SOT-23-5 surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates dual fixed-output LDO regulation with an embedded voltage detector circuit
• Maintains high efficiency through ultra-low quiescent current consumption
• Delivers stable performance with minimal voltage drop under load conditions

Applications

• Battery-powered portable electronic devices requiring efficient power management
• Embedded systems needing simultaneous multiple voltage rails from a single source
• Circuits requiring integrated power-on reset or voltage supervision functions

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct output voltage combinations and package type. Confirm RoHS compliance status and check for any recent Product Change Notifications that may affect specifications or manufacturing locations before finalizing procurement orders.

Selection Notes

Select this component when a design requires two distinct regulated voltages alongside voltage monitoring capabilities in a small footprint. Ensure the input voltage remains within the 2 V to 6.5 V range and that the thermal dissipation requirements fit within the SOT-23-5 package constraints for the expected load currents.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. It is designed for applications where space is limited and power efficiency is critical. The series typically offers various output voltage combinations to suit different logic levels and peripheral requirements in mobile and industrial electronics.

Replacement Considerations

Direct substitutes include other S-1701 series variants with compatible output voltages, such as S-1701D5043-M5T1G or S-1701F5043-M5T1G, provided the voltage levels match the system requirements. Verify pin compatibility and electrical parameters before substitution.
