S-1701B2522-U5T1G

Overview

The S-1701B2522-U5T1G is a dual-output low dropout voltage regulator from the ABLIC S-1701 series, housed in an SOT-89-5 surface-mount package. It provides fixed output voltages of 2.2 V and 2.5 V with a maximum continuous output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and maintains a voltage regulation accuracy of 1%. It operates within a temperature range of -40°C to +85°C and includes built-in voltage detection functions.

Feature Summary

• Dual independent fixed voltage outputs for simultaneous power rail generation
• Integrated voltage detector function for system monitoring
• Low quiescent current consumption for energy efficiency
• High voltage regulation accuracy ensuring stable performance

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered systems needing efficient power management
• Embedded controllers utilizing integrated voltage detection
• Automotive electronics compliant with specific thermal requirements

Procurement Notes

Verify the exact output voltage configuration (2.2V/2.5V) against schematic requirements before ordering. Confirm that the SOT-89-5 package dimensions fit the PCB footprint. Ensure the input voltage exceeds the highest output voltage by the required dropout margin. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Selection Notes

Select this component when two distinct fixed voltages are needed from a single regulator IC to save board space. The 400 mA output capability supports moderate load currents. Consider the 85 µA quiescent current impact on battery life. Verify that the operating temperature range meets the application environment. Compare dropout voltage specifications against the minimum available input voltage.

Part Context

This part belongs to the ABLIC S-1701 series of combo voltage detectors and regulators. These devices integrate linear regulation with voltage monitoring capabilities in a compact form factor. The series is designed for applications requiring reliable power supply management with minimal external components. The S-1701 family offers various output voltage combinations to suit different digital logic levels.

Replacement Considerations

Check for other S-1701 variants with compatible pinouts and similar electrical characteristics. Verify that substitute parts offer equivalent dual-output configurations and current ratings. Ensure replacement components meet the same thermal and regulatory standards.
