S-1701V3430-M5T1G

Overview

The S-1701V3430-M5T1G is a low-dropout (LDO) voltage regulator and voltage detector combo IC from ABLIC. It features two fixed output voltages of 3.4 V and 3.0 V, with a maximum output current of 400 mA. The device operates within an input voltage range of 2 V to 6.5 V and maintains a typical quiescent current of 85 µA. It utilizes an SOT-23-5 package and supports operation temperatures from -40°C to +85°C.

Feature Summary

• Integrates dual LDO regulators with a built-in voltage detector for combined power management and monitoring functions.
• Achieves high efficiency through low on-resistance transistors, enabling low dropout voltage and large output current capability.
• Designed for minimal external component usage, allowing the use of small ceramic capacitors without requiring external delay circuits.

Applications

• Battery-powered portable electronic devices requiring efficient power regulation.
• Systems needing simultaneous voltage stabilization and supply monitoring.
• Compact consumer electronics utilizing small surface-mount packages.

Procurement Notes

Verify the specific output voltage configuration and package type against your schematic requirements before ordering. Confirm that the operating temperature range meets your environmental specifications. Ensure compatibility with your PCB footprint for the SOT-23-5 package. Check for any recent product change notifications or obsolescence notices from the manufacturer.

Selection Notes

Select this component when a single solution for both voltage regulation and detection is required to save board space. Consider the 400 mA output current limit and the specific 3.4 V/3.0 V fixed outputs. Evaluate if the 85 µA quiescent current aligns with your system's power budget. Verify input voltage constraints relative to your battery or supply source.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators by ABLIC. The series is characterized by low power consumption and compact packaging options suitable for modern portable electronics. These ICs combine linear regulation with monitoring capabilities in a single small outline transistor package.

Replacement Considerations

Direct substitutes may include other parts from the S-1701 family with matching output voltages and pin configurations. Verify functional equivalence regarding quiescent current and dropout voltage characteristics before substitution.
