S-1701F3430-M5T1G

Overview

The S-1701F3430-M5T1G is a low-dropout (LDO) voltage regulator and voltage detector combo IC manufactured by ABLIC Inc. It features two fixed output voltages of 3.4 V and 3.0 V, with a maximum output current of 400 mA per channel. The device operates within an input voltage range of 2 V to 6.5 V and maintains a typical quiescent current of 85 µA. Packaged in a compact SOT-23-5 format, it supports surface-mount installation and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual LDO regulators with a combined voltage detection circuit for space-constrained designs.
• Provides high output current capability of 400 mA to support demanding load requirements.
• Maintains ultra-low power consumption through an 85 µA quiescent current specification.

Applications

• Portable electronic devices requiring efficient multi-rail power management
• Battery-operated systems needing extended operational life
• Embedded controllers utilizing integrated supervision and regulation

Procurement Notes

Verify the specific output voltage combination and package type against project requirements before ordering. Confirm compliance with RoHS directives and environmental standards relevant to your region. Ensure thermal management strategies align with the device's power dissipation limits under maximum load conditions. Check for any recent product change notifications that may affect specifications or manufacturing locations.

Selection Notes

Select this component when a single solution is needed for both power regulation and system monitoring. Compare dropout voltage characteristics against other series members if precise headroom is critical. Consider the SOT-23-5 footprint constraints during PCB layout planning. Evaluate the 85 µA standby current benefit for battery-powered applications versus higher-performance alternatives.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. The series is designed to reduce board space by integrating multiple functions into a single package. Similar parts in the family offer different fixed output voltage combinations while maintaining consistent electrical performance and packaging dimensions.

Replacement Considerations

Direct substitutes include other S-1701 variants with identical SOT-23-5 packaging and similar electrical profiles, such as the S-1701F3330-M5T1G or S-1701F3630-M5T1G, provided the specific output voltage differences are acceptable for the application design.
