FAN1582M25X

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The FAN1582M25X is a fixed-output positive linear voltage regulator belonging to the FAN1582 series, manufactured by Fairchild Semiconductor (now onsemi). It provides a fixed output voltage of 2.5 V with a maximum continuous output current of 3 A. The device operates within an input voltage range of 1.75 V to 6.5 V and features a typical dropout voltage of 1.05 V at full load. It utilizes a TO-252-5 surface-mount package and includes internal protection mechanisms against overcurrent and thermal overload.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability issues from discontinued status. Confirm package integrity and pin alignment prior to assembly. Review manufacturer documentation for handling precautions related to electrostatic discharge sensitivity during storage and installation processes.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this regulator when a precise 2.5 V rail is required with moderate current demands. Ensure input voltage remains above the minimum threshold while accounting for dropout characteristics under varying load conditions. Evaluate thermal dissipation requirements based on the difference between input and output voltages multiplied by load current.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This component is part of the FAN1582 family of low-dropout regulators designed for efficiency and reliability. The specific M25X suffix indicates a fixed 2.5 V output variant packaged in TO-252-5.
