S-1701V3430-U5T1G

Overview

The S-1701V3430-U5T1G is a CMOS-based low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, integrating a high-accuracy voltage detector and reset function. It features dual fixed output voltages of 3.0 V and 3.4 V with a maximum output current of 400 mA. The device operates within an input voltage range supporting these outputs and maintains a typical quiescent current of 85 µA. It utilizes an SOT-89-5 package and ensures stable performance across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-accuracy voltage detector with a dedicated reset output function for system protection.
• Provides dual fixed output voltages (3.0 V and 3.4 V) in a single compact package.
• Features ultra-low quiescent current consumption to extend battery life in portable applications.

Applications

• Battery-powered portable electronic devices requiring stable dual voltage rails.
• Microcontroller systems needing integrated power supervision and reset generation.
• Embedded circuits requiring low-noise regulation with minimal standby current drain.

Procurement Notes

Verify the specific suffix U5T1G corresponds to the SOT-89-5 package variant when sourcing. Confirm that the required output voltages match the dual 3.0 V/3.4 V configuration specified for this part number. Ensure compatibility with the operating temperature range of -40°C to +85°C for your application environment.

Selection Notes

Select this component when a single IC solution is needed for both voltage regulation and voltage monitoring. It is suitable for designs where board space is limited and dual LDOs would otherwise be required. Consider the 400 mA output capability against the load requirements of the target circuitry.

Part Context

This part belongs to the S-1701 series of voltage regulators developed by ABLIC Inc. using CMOS technology.
