S-1701D3328-M5T1G

Overview

The S-1701D3328-M5T1G is a low-dropout (LDO) voltage regulator and voltage detector combo IC from the ABLIC S-1701 series. It features two fixed output voltages of 2.8 V and 3.3 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. 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 fixed-output LDO regulation with a combined voltage detection function for space-constrained designs.
• Maintains ultra-low power consumption through an 85 µA quiescent current specification during operation.
• Delivers high drive capability with a 400 mA continuous output current rating for demanding loads.

Applications

• Portable electronic devices requiring efficient multi-rail power management
• Battery-powered systems utilizing low-quiescent-current regulators
• Embedded circuits needing simultaneous voltage monitoring and regulation

Procurement Notes

Verify the specific output voltage combination matches the target application requirements before ordering. Confirm that the SOT-23-5 package footprint aligns with the PCB layout design. Ensure the operating temperature range covers the intended environmental conditions. Check for any recent product change notifications regarding manufacturing updates or material substitutions.

Selection Notes

Select this component when a single package solution is required for both power regulation and system supervision. The dual-output configuration simplifies board layout by reducing component count compared to separate regulator and detector chips. Consider the dropout voltage characteristics relative to the minimum input voltage available in the power supply chain.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators manufactured by ABLIC Inc. The series is designed for applications requiring high integration and low power consumption. Similar parts in the lineup vary primarily by their fixed output voltage pairs and specific pin configurations while sharing the same core regulatory architecture.

Replacement Considerations

Direct substitutes include other S-1701 series variants such as S-1701F3328-M5T1G or S-1701U3328-M5T1G, which offer identical electrical specifications and pinouts but may differ in internal manufacturing revisions. Verify compatibility with existing firmware if the voltage detector threshold behavior is critical to system reset sequences.
