S-1701W3328-M5T1G

Overview

The S-1701W3328-M5T1G is a dual-output low-dropout (LDO) voltage regulator manufactured by ABLIC Inc. It integrates two fixed output channels providing 2.8 V and 3.3 V, with a maximum continuous output current of 400 mA per channel. The device operates within an input voltage range of 2 V to 6.5 V and features a typical quiescent current of 85 µA. It utilizes an SOT-23-5 surface-mount package and supports a junction temperature range from -40 °C to +85 °C. The regulator includes built-in voltage detection capabilities for system monitoring.

Feature Summary

• Dual-channel architecture delivering independent fixed voltages
• Ultra-low standby current consumption for battery efficiency
• Integrated voltage detector function for system supervision

Applications

• Portable electronic devices requiring multiple stable supply rails
• Battery-powered systems needing extended operational life
• Embedded controllers requiring integrated power management and monitoring

Procurement Notes

Verify the specific output voltage combination and package type against your schematic requirements before ordering. Confirm that the thermal dissipation capabilities of the SOT-23-5 package are sufficient for your application's load conditions. Ensure compatibility with the manufacturing process regarding the reel packaging format.

Selection Notes

Select this component when a compact solution is needed for generating two distinct logic or analog supply voltages from a single input source. Consider the dropout voltage characteristics relative to your minimum input voltage to ensure regulation stability under full load conditions.
