FT511AB

Overview

The FT511AB is a linear voltage regulator IC manufactured by Fremont Micro Devices Ltd. It provides a fixed positive output voltage of 1.2V with a maximum output current capability of 150mA. The device is housed in a compact SOT-89-3LA surface-mount package, suitable for space-constrained applications. It operates within a minimum temperature range of -40°C, ensuring reliability in various environmental conditions.

Feature Summary

• Fixed positive output voltage regulation
• Compact SOT-89-3LA surface-mount packaging
• Designed for low-power linear regulation applications

Applications

• Embedded systems requiring stable 1.2V supply
• Battery-powered devices needing efficient linear regulation
• General-purpose power management circuits

Procurement Notes

Verify the exact manufacturer part number and datasheet revision when sourcing. Confirm that the supplier provides original components from Fremont Micro Devices Ltd or authorized distributors. Check for RoHS compliance status if required by your project specifications. Ensure the package type matches the SOT-89-3LA footprint on your PCB design to avoid assembly issues.

Selection Notes

Select this component when a fixed 1.2V output is required with moderate current demands up to 150mA. Consider its linear topology for noise-sensitive applications where switching regulators are unsuitable. Evaluate thermal performance based on the expected voltage drop and ambient temperature, as linear regulators dissipate excess energy as heat. The SOT-89-3LA package offers a balance between size and thermal dissipation capabilities.
