S-1701W3227-M5T1G

Overview

The S-1701W3227-M5T1G is a low-dropout regulator and voltage detector combo IC from ABLIC's S-1701 series. It features two fixed output voltages of 2.7 V and 3.2 V with a maximum output current of 400 mA. The device operates within an input voltage range supporting these outputs, maintaining a typical quiescent current of 85 uA. It utilizes an SOT-23-5 surface-mount package and functions across a temperature range of -40°C to +85°C. Key electrical characteristics include a dropout voltage of 140 mV and line regulation of 0.2% per Volt.

Feature Summary

• Integrates dual fixed-output LDO regulators with a built-in voltage detector in a single compact package.
• Provides high output current capability of 400 mA while maintaining ultra-low standby current consumption.
• Ensures stable power delivery with low dropout voltage performance across the specified operating temperature range.

Applications

• Portable electronic devices requiring efficient power management
• Battery-operated systems needing extended operational life
• Embedded circuits requiring combined regulation and monitoring functions

Procurement Notes

Verify the specific part number against official ABLIC documentation to confirm pinout compatibility and electrical specifications. Ensure that the SOT-23-5 package dimensions align with your PCB footprint requirements. Cross-reference the datasheet for thermal dissipation limits and recommended external capacitor values to guarantee stable operation under your specific load conditions.

Selection Notes

Select this component when a design requires simultaneous voltage regulation and detection in a space-constrained environment. The dual-output configuration simplifies board layout by reducing component count. Consider the 400 mA output current rating to ensure it meets peak load demands without exceeding thermal limits defined in the datasheet.

Part Context

This model belongs to the S-1701 series, which combines LDO regulators with voltage detectors. The series is designed for applications prioritizing low power consumption and high reliability. The W suffix typically indicates the specific package type and tape/reel packaging configuration used for automated assembly processes.

Replacement Considerations

Consult official ABLIC substitution guides for verified alternatives. Generic LDOs may not offer the integrated voltage detector functionality or identical pinout compatibility. Verify that any substitute matches the 400 mA current rating and SOT-23-5 package constraints.
