S-1701V3326-M5T1G

Overview

The S-1701V3326-M5T1G is a dual-output low dropout (LDO) voltage regulator and voltage detector combo IC from ABLIC. It provides fixed output voltages of 2.6 V and 3.3 V with a maximum output current of 400 mA. 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. The unit is housed in a compact SOT-23-5 package and supports surface-mount installation. It functions reliably across a temperature range of -40°C to +85°C, offering high accuracy and stability for portable electronics.

Feature Summary

• Integrates dual LDO regulators with a built-in voltage detector for combined power management and monitoring.
• Delivers high output current capability of 400 mA while maintaining ultra-low quiescent current consumption.
• Provides precise fixed output voltages with tight regulation accuracy for stable system operation.

Applications

• Portable electronic devices requiring efficient multi-rail power supply
• Battery-powered systems needing extended operational life through low standby current
• Embedded controllers requiring integrated voltage supervision and regulation

Procurement Notes

Verify the specific output voltage combination of 2.6 V and 3.3 V matches your design requirements before ordering. Confirm that the SOT-23-5 package footprint aligns with your PCB layout. Ensure the operating temperature range of -40°C to +85°C suits your application environment. Check for any recent product change notifications or obsolescence notices from ABLIC. Validate compatibility with your system's input voltage constraints.

Selection Notes

Select this component when a single solution is needed for both voltage regulation and detection to save board space. Consider the 400 mA output current limit against your peak load requirements. Evaluate the 85 µA quiescent current benefit if battery longevity is critical. Compare the SOT-23-5 package size against available alternatives if space is extremely constrained. Verify that the fixed output voltages meet your logic level requirements without additional adjustment components.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators by ABLIC. The series is designed for portable equipment where power efficiency and component count reduction are priorities. Similar parts in the series offer different fixed output voltage combinations but share the same core architecture and performance characteristics. The S-1701V3326 variant specifically targets applications requiring 2.6 V and 3.3 V rails simultaneously.

Replacement Considerations

Direct substitutes include other S-1701 series parts with identical pinouts and similar electrical specifications but different fixed output voltages. Cross-reference with ABLIC's official replacement guide for equivalent packages and thermal characteristics. Ensure any alternative maintains the 400 mA output current and 85 µA quiescent current specs. Verify that the replacement supports the same SOT-23-5 package and operating temperature range.
