S-1701D3430-M5T1G

Overview

The S-1701D3430-M5T1G is a low-dropout (LDO) voltage regulator manufactured by ABLIC Inc., belonging to the S-1701 series. It features a dual-output configuration providing fixed voltages of 3.0 V and 3.4 V. The device supports an output current of 400 mA with a typical quiescent current of 85 µA. It operates within an input voltage range of 2 V to 6.5 V and maintains a maximum dropout voltage of 140 mV at rated load. The component is housed in an SOT-23-5 surface-mount package and is designed for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a dual-output LDO regulator with a built-in voltage detector function for combined power management and monitoring.
• Provides high efficiency through ultra-low quiescent current consumption, extending battery life in portable applications.
• Ensures stable regulation with low dropout voltage characteristics under varying load conditions.

Applications

• Portable electronic devices requiring efficient dual-voltage power rails
• Battery-powered systems needing integrated voltage supervision
• Embedded circuits utilizing microcontrollers or sensors with specific voltage requirements

Procurement Notes

Verify the exact part number against official ABLIC documentation to confirm pinout compatibility and electrical specifications. Ensure that the SOT-23-5 package footprint matches your PCB design constraints. Confirm operational temperature ranges align with your system environment. Cross-reference datasheet revisions to account for any potential parameter updates or manufacturing changes documented in product change notifications.

Selection Notes

Select this component when a compact solution is required for generating two distinct fixed voltages from a single supply rail. The S-1701D3430-M5T1G is suitable for designs prioritizing low standby current and minimal board space. Consider the 400 mA output capability and the specific 3.0 V/3.4 V output levels to ensure they meet the load requirements of your target circuitry without excessive heat dissipation.

Part Context

This device is part of the ABLIC S-1701 series, which combines LDO regulators with voltage detectors. The series is characterized by low quiescent current and small package options like SOT-23-5 and SOT-89-5. These components are designed for power management in mobile and industrial applications where space and energy efficiency are critical constraints.

Replacement Considerations

Check for direct substitutes within the S-1701 family that offer compatible output voltages and package types. Verify pin-to-pin compatibility before replacing to avoid PCB redesign. Consult official cross-reference lists for confirmed equivalent parts with identical electrical characteristics.
