S-1701V3227-M5T1G

Overview

The S-1701V3227-M5T1G is a dual-output low dropout (LDO) voltage regulator and voltage detector manufactured by ABLIC Inc. It provides fixed output voltages of 2.7 V and 3.2 V with a maximum output current of 400 mA. The device features a typical quiescent current of 85 µA, ensuring efficient power management in battery-operated applications. It operates within an input voltage range supporting these outputs and maintains regulation across a temperature range of -40°C to +85°C. The component utilizes a compact SOT-23-5 surface-mount package, suitable for space-constrained designs requiring reliable voltage supervision and regulation.

Feature Summary

• Integrates dual fixed-output LDO regulators with a built-in voltage detector function
• Delivers high output current capability up to 400 mA per channel
• Maintains ultra-low quiescent current for extended battery life
• Provides precise voltage monitoring for system reset and supervision

Applications

• Portable electronic devices requiring multi-voltage rails
• Battery-powered systems needing voltage supervision
• Embedded controllers requiring stable logic supply voltages
• IoT modules with strict power consumption constraints

Procurement Notes

Verify the specific output voltage combination of 2.7 V and 3.2 V against schematic requirements. Confirm the SOT-23-5 package footprint matches the PCB layout. Ensure the operating temperature range meets the environmental specifications of the target application. Check for RoHS compliance status if required by project standards.

Selection Notes

Select this component when dual independent regulated outputs are needed alongside voltage detection. Compare dropout voltage characteristics against minimum input voltage constraints. Evaluate thermal performance based on expected load currents and ambient temperatures. Consider the 85 µA quiescent current impact on overall system efficiency during standby modes.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. The series offers various fixed output voltage combinations tailored for different logic families and sensor interfaces. The S-1701V suffix indicates the specific voltage pair configuration within the product line.

Replacement Considerations

Direct substitutes must match the 2.7 V/3.2 V output combination, 400 mA current rating, and SOT-23-5 package. Verify pinout compatibility and electrical parameters such as quiescent current and dropout voltage before substitution.
