Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for FAN1084DX

FAN1084DX

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

The FAN1084DX is an adjustable positive low dropout linear regulator manufactured by Fairchild Semiconductor, now part of ON Semiconductor. It provides a maximum output current of 1.5 A with a typical dropout voltage of 1.5 V at full load. The device operates within an input voltage range up to 5.75 V and supports an adjustable output voltage from 1.25 V to 5.7 V. It features a TO-252 (DPAK) surface-mount package and includes on-chip thermal limiting for overload protection.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Adjustable positive output voltage capability
Low dropout voltage performance at high current loads
Integrated thermal limiting protection against excessive junction temperatures

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

Post-regulator for switching power supplies
Low voltage VCC logic supply circuits
Battery-powered circuitry requiring stable regulation

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

Verify the manufacturer designation as Fairchild Semiconductor or ON Semiconductor, as corporate acquisitions may affect labeling. Confirm the specific suffix 'DX' corresponds to the TO-252 DPAK package and reel packaging configuration. Ensure the component meets RoHS compliance requirements for your assembly process.

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

Select this component when a fixed 1.5V or 3.3V LDO is insufficient and an adjustable output between 1.25V and 5.7V is required. It is suitable for applications needing 1.5A continuous current with minimal input-to-output voltage differential. Consider the TO-252 package for surface-mount PCB designs where space efficiency is prioritized over the higher power dissipation capacity of through-hole packages.

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

This device belongs to the FAN1084 series of low dropout regulators, which also includes fixed-voltage variants such as the FAN1084-1.5 and FAN1084-3.3. The series is optimized for low voltage microprocessor applications and bus termination where transient response and minimum input voltage are critical design constraints.
