S-1701W3025-U5T1G

Overview

The S-1701W3025-U5T1G is a low-dropout regulator from the ABLIC S-1701 series, featuring dual fixed outputs of 2.5 V and 3.0 V. It delivers a maximum output current of 400 mA with a typical quiescent current of 85 µA. The device operates within an input voltage range supporting these outputs and maintains a dropout voltage of 160 mV at rated load. Voltage regulation accuracy is specified at 1%, with line regulation at 0.2%/V and load regulation at 40 mV. It functions in temperatures from -40°C to +85°C and is housed in an SOT-89-5 package.

Feature Summary

• Integrates dual independent voltage regulators for simultaneous supply generation
• Provides ultra-low standby current consumption for battery-powered applications
• Ensures stable operation with minimal voltage drop under load conditions

Applications

• Portable electronic devices requiring multiple logic supply rails
• Battery-operated systems needing extended operational life
• Embedded circuits requiring precise voltage monitoring and regulation

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and thermal characteristics. Ensure the ordering quantity aligns with manufacturer reel specifications. Cross-reference the datasheet revision date to validate regulatory compliance status before integration into production designs.

Selection Notes

Select this component when dual isolated outputs are required from a single regulator footprint. Compare dropout voltage requirements against the expected input-output differential. Evaluate thermal dissipation capabilities within the SOT-89-5 package relative to the total power loss generated by the combined output currents.

Part Context

This part belongs to the S-1701 series of combo voltage detector/regulators. The series is designed for applications requiring both power management and voltage supervision. It complements other ABLIC PMIC solutions by offering integrated detection alongside regulation in a compact form factor suitable for space-constrained mobile electronics.

Replacement Considerations

Direct substitutes include S-1701B3025-U5T1G and S-1701R3025-U5T1G, which share identical electrical specifications and pinouts but may differ in manufacturing lot or minor packaging tolerances. Verify functional equivalence through official cross-reference lists.
