S-1701U5040-U5T1G

Overview

The ABLIC S-1701U5040-U5T1G is a dual-output low dropout (LDO) voltage regulator featuring integrated voltage detection capabilities. It provides fixed output voltages of 4.0 V and 5.0 V with a maximum output current of 400 mA per channel. The device operates within an input voltage range supporting these outputs, maintaining a typical quiescent current of 85 µA. It utilizes an SOT-89-5 surface-mount package and ensures stable regulation across an operating temperature range from -40°C to +85°C.

Feature Summary

• Combines dual LDO regulators with voltage detection functions in a single compact package
• Maintains low power consumption through minimal quiescent current draw during operation
• Provides high accuracy fixed output voltages suitable for sensitive digital logic supplies

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Battery-powered systems needing efficient power management
• Embedded circuits utilizing voltage monitoring for system integrity

Procurement Notes

Verify the specific suffix U5T1G corresponds to the SOT-89-5 package configuration. Confirm that the required output voltages match the 4.0 V and 5.0 V combination specified for this part number. Ensure thermal management strategies account for the power dissipation limits inherent to the SOT-89-5 form factor under maximum load conditions.

Selection Notes

Select this component when dual independent regulated outputs are required alongside voltage supervision. The SOT-89-5 package offers a balance between current handling capability and board space efficiency compared to smaller packages. Consider the 400 mA output capacity against the total system load requirements to ensure adequate headroom for transient currents.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators by ABLIC. The series is designed for applications requiring both precise voltage regulation and monitoring functionality. The U5T1G suffix indicates the specific packaging and taping configuration used for automated assembly processes.

Replacement Considerations

Direct replacements must match the dual-output voltage levels of 4.0 V and 5.0 V. Verify compatibility with the SOT-89-5 footprint if pinout differences exist in alternative candidates. Ensure equivalent quiescent current and dropout voltage characteristics to maintain system power efficiency.
