S-1701W3326-M5T1G

Overview

The S-1701W3326-M5T1G is a dual-output low-dropout (LDO) voltage regulator and voltage detector integrated circuit manufactured by ABLIC. It provides two fixed output voltages of 2.6 V and 3.3 V with a maximum output current of 400 mA per channel. The device features a low quiescent current of 85 µA, ensuring efficient power management in battery-operated applications. It operates within an input voltage range of 2 V to 6.5 V and maintains a typical dropout voltage of 140 mV at rated load. The unit is housed in a compact SOT-23-5 surface-mount package, suitable for space-constrained designs.

Feature Summary

• Integrates dual LDO regulators with a built-in voltage detector function in a single package
• Delivers high output current capability of up to 400 mA for demanding loads
• Maintains ultra-low quiescent current consumption of 85 µA for extended battery life
• Provides precise voltage regulation with 1% accuracy across the operating temperature range

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered systems needing efficient power management and monitoring
• Embedded controllers utilizing combined regulation and reset signal generation
• Consumer electronics with strict space and power constraints

Procurement Notes

Verify the specific output voltage combination of 2.6 V and 3.3 V against design requirements before procurement. Confirm that the SOT-23-5 package footprint matches the PCB layout. Ensure the input voltage supply remains within the 2 V to 6.5 V operational limits to prevent malfunction. Check for any recent product change notifications or pinout revisions from ABLIC prior to finalizing orders.

Selection Notes

Select this component when dual fixed outputs are required alongside voltage supervision functionality. The 400 mA current rating supports moderate load applications without external pass transistors. Consider the thermal dissipation capabilities in the SOT-23-5 package under high load conditions. This part is suitable for designs prioritizing low standby current and compact form factor over adjustable output flexibility.

Part Context

This device belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. The series is designed to replace discrete solutions by integrating regulation and detection functions. The S-1701W3326 variant specifically targets applications requiring 3.3 V logic levels and lower voltage rails. It complements other parts in the family like the S-1701Q and S-1701N series which offer different voltage combinations.

Replacement Considerations

Direct substitutes include other S-1701 series variants with identical SOT-23-5 packaging and similar electrical characteristics, such as S-1701D5043-M5T1G or S-1701F5043-M5T1G, provided the output voltage differences are acceptable for the application.
