AP1086T50L-U

Overview

The AP1086T50L-U is a fixed-mode low dropout positive regulator manufactured by Diodes Incorporated. It provides a fixed output voltage of 5.0V with a maximum output current capability of 1.5A. The device operates within an input voltage range of 4.7V to 12V and maintains regulation with a maximum dropout voltage of 1.4V at full load. It utilizes a TO-220-3L through-hole package and supports an operating junction temperature range from 0°C to +125°C.

Feature Summary

• Provides stable power for low voltage IC applications including high-speed bus termination and logic supplies
• Incorporates built-in thermal shutdown and output current limiting protection mechanisms
• Features fast transient response characteristics to handle rapid load changes

Applications

• High-speed bus termination circuits
• Low current 3.3V logic supply generation
• VGA card power management systems

Procurement Notes

Verify the specific suffix configuration against official datasheets, as ordering codes define critical parameters such as package type, output voltage tolerance, and packaging format. Confirm RoHS compliance status and lead-free finish requirements prior to integration into designs to ensure adherence to environmental regulations and manufacturing standards.

Selection Notes

Select this component when a fixed 5.0V output is required with up to 1.5A capacity in a through-hole form factor. Ensure the input voltage remains above the minimum threshold to maintain the specified dropout performance. Evaluate thermal resistance values to determine appropriate heat sinking strategies for continuous operation under maximum load conditions.

Part Context

This part belongs to the AP1086 series of low dropout linear regulators designed for efficient power management. The series offers both adjustable and fixed voltage options across various packages. The T50 designation specifically indicates the TO-220-3L package variant configured for a fixed 5.0V output level.
