FAN1086D33X

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

The FAN1086D33X is a fixed-output low dropout linear regulator manufactured by Fairchild Semiconductor, providing a stable 3.3V output with a maximum current capability of 1.5A. It operates within an input voltage range up to 7.5V and features a typical dropout voltage of 1.3V at full load. The device is housed in a TO-252 (DPAK) surface-mount package, suitable for space-constrained designs. It includes built-in thermal limiting protection to prevent damage during overload conditions.

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

Verify the manufacturer origin as Fairchild Semiconductor or its successor entities like ON Semiconductor due to corporate acquisitions. Confirm the specific suffix 'X' denotes the tape and reel packaging format if required for automated assembly. Ensure the component meets RoHS compliance standards relevant to the target market before finalizing procurement orders.

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

Select this component when a fixed 3.3V rail is needed with moderate current demands up to 1.5A. It is appropriate for applications requiring low dropout performance from a 5V or lower input source. Consider the TO-252 package for surface mount assembly where thermal dissipation needs are manageable without a large heatsink.

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

This part belongs to the FAN1086 series of three-terminal low dropout regulators. The series includes adjustable versions and other fixed voltage options such as 2.5V, 2.85V, and 5.0V. These devices are designed for efficiency in low voltage environments, offering better performance than traditional PNP-type regulators by minimizing quiescent current waste.

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

Compatible substitutes include the LD1086DT33TR from STMicroelectronics and the AP1086D33LA from Diodes Incorporated. Verify pinout compatibility and thermal characteristics when replacing, as package dimensions and thermal resistance may vary slightly between manufacturers.
