S-1701A5040-U5T1G

Overview

The S-1701A5040-U5T1G is a dual-output low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, manufactured by ABLIC Inc. It provides fixed output voltages of 4.0 V and 5.0 V with a maximum output current of 400 mA. The device features a typical quiescent current of 85 µA and operates within an input voltage range of 2 V to 6.5 V. It is housed in a compact SOT-89-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates two independent fixed-voltage LDO regulators and a voltage detector function within a single component.
• Maintains low power consumption through a minimal quiescent current specification suitable for battery-operated systems.
• Ensures stable regulation with low dropout voltage characteristics across varying load conditions.

Applications

• Portable electronic devices requiring multiple regulated supply rails
• Battery-powered equipment needing efficient power management
• Embedded systems utilizing combined voltage regulation and monitoring

Procurement Notes

Verify the specific output voltage combination and package type against your schematic requirements before ordering. Confirm that the SOT-89-5 footprint matches your PCB layout constraints. Ensure the operating temperature range meets your application's environmental specifications. Check for any recent product change notifications regarding pinout or electrical parameters.

Selection Notes

Select this component when a dual-output solution with integrated voltage detection is required in a small form factor. Compare the dropout voltage and load regulation specifications against other LDOs if precise voltage stability under heavy loads is critical. Consider the thermal dissipation capabilities of the SOT-89-5 package relative to your expected power loss.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is designed to provide cost-effective and space-saving solutions for applications requiring both power regulation and system monitoring functions. ABLIC utilizes advanced CMOS technology to achieve high reliability and low power consumption in these integrated circuits.

Replacement Considerations

Direct substitutes may include other parts from the S-1701 family with different output voltage combinations, such as S-1701E5042-U5T1G or S-1701Y3342-U5T1G, provided the voltage levels match the design requirements. Always verify pin compatibility and electrical specifications before substituting.
