The AMS1086CT-2.5 is a low dropout voltage regulator produced by Advanced Monolithic Systems (AMS). It's designed to provide a regulated 2.5V output voltage with a current capability of up to 1.5A. This regulator is suitable for various applications requiring a stable and efficient 2.5V power supply.

Applications

• Post Regulation for Switching Supplies: Cleaning up the output of switching power supplies to reduce noise and ripple.
• Battery-Powered Systems: Providing a regulated voltage from battery sources.
• Microprocessor Core Voltage: Supplying power to microprocessor cores requiring 2.5V.
• Memory Power: Regulating the power supply for memory devices, such as SDRAM and DDR memory.
• Hard Disk Drives: Providing a stable 2.5V supply for certain hard disk drive components.

Features

• Low Dropout Voltage: Ensures the regulator can maintain its output voltage even with a small difference between input and output voltage.
• 1.5A Output Current: Capable of delivering up to 1.5A of continuous output current.
• Internal Thermal Overload Protection: Protects the regulator from damage due to excessive temperature.
• Current Limiting: Limits the output current to protect the regulator and the load from overcurrent conditions.
• Fixed 2.5V Output: Provides a stable and precise 2.5V output voltage.

Benefits

• High Efficiency: Minimizes power dissipation and heat generation, improving overall system efficiency.
• Reliable Power: Provides a stable and reliable 2.5V supply, ensuring consistent operation of powered devices.
• Overload Protection: Protects against damage from overcurrent and overtemperature conditions.
• Simple Design: Requires minimal external components, simplifying the design process.

Additional Details

The AMS1086CT-2.5 is available in a TO-220 package. It is recommended to use an output capacitor for stability, typically a tantalum or aluminum electrolytic capacitor with a value between 10μF and 100μF. A heatsink may be required depending on the input voltage, output current, and ambient temperature to ensure the regulator operates within its safe operating area.
