S-1701A3326-M5T1G

Overview

The S-1701A3326-M5T1G is a dual-output low dropout (LDO) voltage regulator from the ABLIC S-1701 series, designed for power management applications. It integrates two fixed output voltages of 2.6 V and 3.3 V within a single package. The device supports a maximum output current of 400 mA per channel with a typical quiescent current of 85 µA. It operates within an input voltage range of 2 V to 6.5 V and features a dropout voltage of 140 mV at rated load. The component provides high voltage regulation accuracy of 1% and includes built-in voltage detection functionality. It is housed in a compact SOT-23-5 surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates dual fixed LDO regulators with combined voltage detector functionality
• Maintains low quiescent current consumption for battery-powered efficiency
• Provides stable regulation with minimal dropout voltage under load
• Ensures precise output voltage stability across operating temperature ranges

Applications

• Portable electronic devices requiring multiple regulated supply rails
• Battery-operated systems needing efficient power management
• Embedded circuits utilizing voltage monitoring for system integrity
• Compact consumer electronics with space-constrained PCB layouts

Procurement Notes

Verify the complete part number including suffixes such as M5T1G to ensure correct packaging and pin configuration. Confirm that the required output voltages match the specific variant, as the S-1701 series offers numerous combinations. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the selected distributor provides genuine components with traceable documentation to avoid counterfeit risks.

Selection Notes

Select this component when dual independent voltage outputs are needed from a single source to save board space. Consider the 400 mA current capability against your peak load requirements to prevent thermal issues. Evaluate the 140 mV dropout characteristic against your minimum input voltage constraints. Verify that the SOT-23-5 package fits your assembly footprint and that the operating temperature range meets your environmental specifications.

Part Context

This device belongs to the ABLIC S-1701 series of combo voltage detectors and regulators. These parts are engineered to replace separate regulator and supervisor ICs, reducing component count. The series is characterized by low power consumption and high precision, making it suitable for modern portable electronics. ABLIC specializes in analog semiconductor solutions for automotive and industrial markets.

Replacement Considerations

Direct replacements must match the dual-output configuration (2.6 V/3.3 V), 400 mA current rating, and SOT-23-5 package. Verify equivalent quiescent current and dropout voltage characteristics. Cross-reference with other S-1701 variants if different voltage combinations are acceptable.
