FT531EA

Overview

The FT531EA is a fixed-output linear low-dropout regulator manufactured by Fremont Micro Devices Ltd. It provides a fixed 2.5V output with a maximum continuous current of 250mA. The device features a maximum input voltage rating of 6V and operates within a temperature range of -40°C to 85°C. Key electrical specifications include a quiescent current of 36µA, a typical dropout voltage of 0.14V at 100mA, and power supply rejection ratios ranging from 72dB to 60dB between 1kHz and 10kHz. It is housed in an SOT-23-5 surface-mount package.

Feature Summary

Integrated overcurrent protection for circuit safeguarding
Dediable control feature for power management optimization
Low quiescent current operation for efficiency

Applications

Battery-powered portable electronics
Embedded systems requiring stable 2.5V logic levels
Noise-sensitive analog signal conditioning circuits

Procurement Notes

Verify component authenticity through authorized distribution channels due to the part's obsolete status. Confirm that replacement units meet original electrical specifications, particularly dropout voltage and thermal performance. Ensure compatibility with existing PCB footprints and soldering profiles. Review manufacturer product change notices for any historical revisions affecting pinouts or materials.

Selection Notes

Select this component when a fixed 2.5V rail is required with minimal external components. Consider the SOT-23-5 package constraints for thermal dissipation at full load. Evaluate the 6V input limit against system supply variations. Verify that the 250mA current capability aligns with peak load requirements without exceeding thermal limits.

Part Context

This component belongs to the FT531 series of positive fixed linear regulators. It shares architectural similarities with variants offering different output voltages, such as the FT531AA (1.2V). The series is characterized by low noise and high PSRR, designed for applications where clean power delivery is critical despite limited input voltage headroom.
