S-1701A2520-U5T1G

Overview

The S-1701A2520-U5T1G is a dual-output low dropout (LDO) voltage regulator from ABLIC, integrating a fixed voltage regulator and a voltage detector in a single package. It provides two positive fixed output voltages of 2.0 V and 2.5 V with a maximum output current of 400 mA. The device features a typical quiescent current of 85 uA and operates within an ambient temperature range of -40°C to +85°C. It utilizes an SOT-89-5 surface-mount package and offers a line regulation of 0.2%/V and load regulation of 40 mV.

Feature Summary

• Integrates a dual-output LDO regulator and a voltage detector function for combined power management and monitoring.
• Provides fixed positive output voltages with high accuracy and stable performance under varying load conditions.
• Features ultra-low quiescent current consumption to extend battery life in portable applications.

Applications

• Portable electronic devices requiring efficient power management
• Battery-powered systems needing voltage monitoring and regulation
• Embedded circuits requiring stable dual-voltage supplies

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. Ensure the operating temperature range meets your application's environmental specifications. Check for any recent product change notifications or obsolescence notices from ABLIC.

Selection Notes

Select this component when a compact solution combining regulation and detection is needed. Compare dropout voltage characteristics at your expected load current against other LDO options. Consider the thermal dissipation capabilities of the SOT-89-5 package relative to your power budget. Verify compatibility with your system's input voltage range.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is designed for applications requiring both power regulation and voltage supervision in a small form factor. It complements ABLIC's broader portfolio of PMIC solutions for consumer and industrial electronics.

Replacement Considerations

Check for direct pin-compatible alternatives within the S-1701 family with different voltage outputs. Verify if newer revisions of the same part number are available. Cross-reference with other dual-output LDOs offering similar current ratings and package types.
