S-1701W2522-U5T1G

Overview

The S-1701W2522-U5T1G is a dual-output low-dropout (LDO) 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 operates within a temperature range of -40°C to +85°C. Key electrical specifications include a line regulation of 0.2%/V, load regulation of 40 mV, and a power dissipation rating of 1 W.

Feature Summary

• Integrates two independent linear regulators into a single compact component for space-constrained designs.
• Combines voltage regulation functionality with built-in voltage detection capabilities for system monitoring.
• Maintains stable performance with low quiescent current consumption suitable for battery-powered applications.

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Embedded systems utilizing combined power management and voltage supervision
• Industrial equipment operating within standard commercial temperature ranges

Procurement Notes

Verify the specific output voltage configuration against official datasheets, as suffixes may indicate variations. Confirm RoHS compliance status and packaging details such as reel quantity before ordering. Ensure thermal management requirements are met given the 1 W power dissipation limit in the SOT-89-5 package.

Selection Notes

Select this component when dual fixed outputs are required alongside voltage detection functions. Compare dropout voltage characteristics against similar models if input voltage headroom is limited. Consider the SOT-89-5 package size constraints relative to PCB layout requirements.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. It shares architectural similarities with other variants like the S-1701W2521-U5T1G but differs in specific output voltage settings. The series is designed for applications needing integrated power regulation and monitoring in small form factors.

Replacement Considerations

Direct substitutes within the same series include parts with identical pinouts and functional blocks but different output voltage combinations, such as the S-1701W2521-U5T1G. Verify that alternative parts meet the same thermal and electrical specifications for seamless integration.
