S-1701W2521-M5T1G

Overview

The S-1701W2521-M5T1G is a low dropout CMOS voltage regulator with an integrated voltage detector, manufactured by ABLIC. It features two fixed output voltages of 2.1 V and 2.5 V, delivering a maximum output current of 400 mA. The device operates within an input voltage range of 2 V to 6.5 V and maintains a typical quiescent current of 85 µA. Key electrical specifications include a line regulation of 0.2 %/V, load regulation of 40 mV, and a power dissipation capability of 1 W. It functions reliably across a temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates a high ripple rejection low dropout voltage regulator with a reset function for combined power management and system monitoring.
• Provides dual fixed output channels (2.1 V and 2.5 V) in a single compact package to reduce board space.
• Features ultra-low current consumption of 85 µA to extend battery life in portable applications.

Applications

• Battery-powered portable electronic devices requiring efficient power management.
• Embedded systems needing simultaneous stable voltage rails and voltage supervision.
• Automotive electronics components requiring reliable operation under varying load conditions.

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout compatibility and thermal characteristics. Ensure the ordering quantity aligns with manufacturer reel requirements. Confirm RoHS compliance status through the latest environmental documentation provided by ABLIC before finalizing procurement plans.

Selection Notes

Select this component when dual fixed outputs are required alongside voltage detection functionality. Compare dropout voltage specifications against the minimum input voltage available in the target circuit. Evaluate thermal performance based on the 1 W power dissipation limit and the SOT-23-5 package constraints for the intended operating environment.

Part Context

This part belongs to the S-1701 series of linear regulators from ABLIC, designed for general-purpose and automotive applications. The series emphasizes low current consumption and high reliability, often featuring AEC-Q100 qualification for automotive use. It serves as a solution for managing power distribution and system resets in compact electronic designs.

Replacement Considerations

Check for direct substitutes within the S-1701 family that match the 2.1 V/2.5 V output combination. Verify equivalent packages such as SOT-23-5 or SOT-89-5 if form factor changes are permissible. Ensure replacement parts maintain similar quiescent current and dropout voltage specifications.
