S-1701B3327-M5T1G

Overview

The S-1701B3327-M5T1G is a dual-output low dropout (LDO) voltage regulator manufactured by ABLIC. It integrates two fixed output voltages of 3.3 V and 2.7 V within a single package. The device provides a maximum output current of 400 mA with an ultra-low quiescent current of 85 µA. It operates within an input voltage range of 2 V to 6.5 V and features a typical dropout voltage of 140 mV at 100 mA. The component supports surface-mount installation in an SOT-23-5 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual fixed output channels for simultaneous voltage regulation and monitoring
• Ultra-low quiescent current consumption for extended battery life
• Compact SOT-23-5 surface-mount package design
• High accuracy voltage regulation with integrated voltage detector functionality

Applications

• Battery-powered portable electronic devices requiring efficient power management
• Embedded systems needing stable reference voltages for microcontrollers
• Circuits requiring combined regulated power supply and voltage supervision
• Consumer electronics with strict space and power constraints

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and thermal characteristics. Ensure the selected variant matches the required output voltage combination and package type for your PCB layout. Cross-reference the datasheet revision history for any recent manufacturing changes or updates that may affect performance specifications.

Selection Notes

Select this component when a dual-output solution is required to save board space and reduce component count. The 400 mA output capability suits moderate load applications, while the 85 µA quiescent current makes it suitable for energy-sensitive designs. Confirm that the input voltage range covers your system's operational requirements and that the thermal dissipation in the SOT-23-5 package is adequate for your expected load conditions.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. The series is designed to provide both power regulation and voltage monitoring functions in a compact form factor. It targets applications where space efficiency and low power consumption are critical, offering a consolidated solution compared to using separate regulator and detector ICs.

Replacement Considerations

Check for direct substitutes within the S-1701 family with matching output voltages and packages. Verify pin-to-pin compatibility before replacing existing components. Consider alternative LDOs with similar current ratings and quiescent currents if exact matches are unavailable.
