S-1701W2520-U5T1G

Overview

The S-1701W2520-U5T1G is a dual-output low-dropout (LDO) voltage regulator manufactured by ABLIC. It integrates two independent fixed output voltages of 2.0 V and 2.5 V within a single package. The device supports a maximum output current of 400 mA per channel with an input voltage range typically extending up to 6.0 V. Key electrical specifications include a quiescent current of 85 µA, a line regulation of 0.2 %/V, and a load regulation of 40 mV. The unit operates within a temperature range of -40 °C to +85 °C and features a power dissipation rating of 1 W.

Feature Summary

• Integrates two independent LDO regulators in a single package for space-constrained designs
• Provides high output current capability of 400 mA per channel
• Features ultra-low quiescent current of 85 µA for efficient power management
• Includes built-in voltage detection function for system monitoring

Applications

• Portable electronic devices requiring multiple voltage rails
• Battery-powered systems needing extended operational life
• Embedded circuits requiring compact power management solutions
• Systems utilizing voltage detectors for status monitoring

Procurement Notes

Verify the specific output voltage combination against the official datasheet before ordering, as suffixes define precise voltage pairs. Confirm the package type matches the design requirements, noting that this model utilizes the SOT-89-5 package. Ensure thermal management strategies account for the 1 W power dissipation limit under expected operating conditions. Cross-reference the manufacturer part number with distributor catalogs to ensure availability and correct revision levels.

Selection Notes

Select this component when a dual-rail power supply is required within a minimal footprint. The 400 mA output current capacity suits moderate load applications. Consider the 85 µA quiescent current for battery-operated devices where standby power consumption is critical. Verify that the required output voltages align with the available combinations in the S-1701 series catalog. Evaluate thermal performance based on the ambient temperature and power dissipation constraints.

Part Context

This part belongs to the S-1701 series of combo voltage detector/regulator ICs from ABLIC. The series is designed for portable equipment, offering integrated regulation and detection functions. Variants within the series differ primarily in output voltage combinations and package types, such as SOT-89-5 or SOT-23-5. The S-1701W2520-U5T1G specifically provides 2.0 V and 2.5 V outputs in the SOT-89-5 form factor.

Replacement Considerations

Direct replacements must match the dual-output configuration, 400 mA current rating, and SOT-89-5 package. Check ABLIC's product lineup for other S-1701 variants with compatible voltage pairs. Ensure any substitute maintains the same quiescent current and thermal characteristics.
