Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for FAN1581T25

FAN1581T25

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

The FAN1581T25 is a linear voltage regulator IC providing a fixed positive output of 2.5V with a maximum current capability of 5A. It utilizes a TO-252-5 (DPAK) surface-mount package. The device features an input voltage range up to 7V and exhibits a typical dropout voltage of 0.4V at full load, with a maximum specified dropout of 1.18V at 5A. Quiescent current is typically 6 mA, and power supply rejection ratio reaches 80dB at 120Hz. Operating temperature spans from 0°C to 125°C.

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

Verify component status as the base FAN1581 series may be obsolete. Confirm exact suffix compatibility for tape and reel packaging requirements. Ensure sourcing channels provide valid manufacturer traceability documents. Check for RoHS compliance status in official datasheets before integration into production designs.

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

Select this regulator for circuits requiring stable 2.5V output under high current loads. Consider the TO-252-5 package for surface mount assembly constraints. Evaluate thermal management needs given the 5A output capability and dropout characteristics. Verify input voltage stability remains within the 7V maximum limit during operation.

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

This component belongs to the FAN1581 family of ultra-low dropout linear regulators manufactured by onsemi. The family includes adjustable and fixed variants such as 1.2V and 1.5V versions designed for specific bus termination standards. The T25 suffix denotes the fixed 2.5V output configuration housed in the DPAK package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes include other 5A LDOs with similar 2.5V fixed outputs and TO-252-5 packages. Verify pinout compatibility and thermal resistance values when cross-referencing with alternative manufacturers' components.
