S-1701F3328-M5T1G

Overview

The S-1701F3328-M5T1G is a low-dropout (LDO) voltage regulator and voltage detector combo IC manufactured by ABLIC Inc. It features an ultra-low quiescent current of 85 uA and a maximum output current of 400 mA. The device provides two fixed output voltages: 2.8 V for the LDO regulator and 3.3 V for the voltage detector threshold. It operates within a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 package.

Feature Summary

• Integrates a low-dropout regulator with a built-in voltage detector function
• Achieves ultra-low power consumption through minimal quiescent current design
• Provides stable regulated output with high current drive capability

Applications

• Battery-powered portable electronic devices requiring extended standby life
• Microcontroller system power management with reset monitoring
• Embedded systems needing combined regulation and voltage supervision

Procurement Notes

Verify the specific output voltage configuration matches the target application requirements, as the part number encodes distinct regulator and detector thresholds. Confirm that the SOT-23-5 package footprint aligns with the PCB layout constraints. Ensure thermal dissipation capabilities are sufficient for the expected load conditions within the specified operating temperature range.

Selection Notes

Select this component when both voltage regulation and under-voltage detection are required in a single package to save board space. Consider the 85 uA quiescent current for applications prioritizing energy efficiency over transient response speed. Evaluate the 400 mA output limit against peak load demands to ensure adequate headroom without exceeding thermal limits.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. The series is designed for applications demanding low power consumption and compact form factors. Similar parts in the series vary primarily in their fixed output voltage settings for both the regulator and detector functions while maintaining consistent electrical characteristics and packaging.

Replacement Considerations

Direct substitutes include other S-1701 series variants with matching pinouts and similar electrical specifications, such as the S-1701F3329-M5T1G or S-1701R3328-M5T1G, provided the specific voltage thresholds meet the circuit design requirements.
