Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for FAN1117AT18

FAN1117AT18

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

The FAN1117AT18 is a fixed-output low dropout linear regulator manufactured by Fairchild Semiconductor, now part of onsemi. It provides a stable 1.8 V output with a maximum current capability of 1 A. The device operates within an input voltage range of 2.5 V to 17 V and features a maximum dropout voltage of 1.2 V at full load. It utilizes a TO-220-3 through-hole package, suitable for applications requiring robust thermal performance and high current delivery in power management circuits.

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

Verify component authenticity due to potential obsolescence or legacy status. Confirm package integrity and pin alignment for TO-220-3 mounting. Check datasheet revisions for any parameter updates. Ensure supplier documentation matches the specific Fairchild/onsemi manufacturing origin. Validate thermal requirements against application constraints before integration.

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

Select this component when a fixed 1.8 V output is required with up to 1 A capacity. Consider the TO-220-3 package for through-hole assembly and superior thermal handling compared to surface-mount alternatives. Evaluate input voltage stability to ensure it remains within the 2.5 V to 17 V operational window. Assess thermal dissipation needs given the linear regulation topology.

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

The FAN1117A series includes adjustable and fixed variants such as -1.8, -2.5, -2.85, -3.3, and -5 V outputs. The AT suffix typically denotes the TO-220-3 through-hole package variant. This family serves as a standard solution for low-noise, high-current linear regulation in industrial and consumer electronics.

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

Compatible substitutes include other 1.8 V, 1 A LDOs in TO-220 packages. Verify pinout compatibility and thermal resistance specifications. Ensure replacement devices meet the same input voltage and dropout voltage requirements.
