S-1701G3331-M5T1G

Overview

The S-1701G3331-M5T1G is a low-dropout regulator and voltage detector combo IC from ABLIC's S-1701 series. It features an ultra-low quiescent current of 85 µA and supports a maximum output current of 400 mA. The device provides two fixed outputs: 3.1 V and 3.3 V. It operates within an input voltage range of 2 V to 6.5 V and delivers a typical dropout voltage of 140 mV at rated load. The component is housed in a compact SOT-23-5 package, suitable for space-constrained power management applications.

Feature Summary

• Integrates dual fixed-output LDO regulation with a built-in voltage detector function
• Maintains ultra-low standby current consumption for extended battery life
• Provides stable performance with minimal voltage drop under high load conditions

Applications

• Battery-powered portable electronic devices requiring efficient power management
• Mobile communication equipment needing reliable voltage supervision
• Embedded systems utilizing CMOS technology for low-power operation

Procurement Notes

Verify the specific suffix M5T1G corresponds to the reel packaging configuration required for your assembly line. Confirm that the dual output voltages of 3.1 V and 3.3 V align with your circuit design specifications before finalizing the order. Ensure compatibility with the SOT-23-5 footprint during PCB layout validation.

Selection Notes

Select this component when both regulated power supply and voltage monitoring are required in a single package. The 400 mA output capability suits moderate load applications, while the 85 µA quiescent current optimizes efficiency in standby modes. Consider the 140 mV dropout characteristic for input voltage headroom calculations relative to the minimum operating voltage.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators manufactured by ABLIC Inc. The series utilizes CMOS technology to achieve high accuracy and low power consumption. The S-1701G3331-M5T1G specifically combines the regulatory and detection functions into one compact solution, reducing component count compared to discrete implementations.

Replacement Considerations

Direct substitutes include other S-1701 series variants with matching output voltages and package types, such as S-1701D3331-M5T1G or S-1701N3331-M5T1G, provided the electrical parameters meet the application requirements.
