The AMS1587CT-3.3 is a 3.3V fixed-output, low dropout voltage regulator manufactured by Advanced Monolithic Systems (AMS). This regulator is designed to provide a stable and regulated 3.3V output voltage with a high output current capability, making it suitable for a wide range of applications requiring a reliable power supply.

Applications

• Powering Microcontrollers and Microprocessors: Providing a stable 3.3V supply to microcontrollers and microprocessors in embedded systems.
• Post Regulation for Switching Power Supplies: Filtering and regulating the output of switching power supplies to reduce noise and ripple.
• Battery-Powered Devices: Regulating voltage in battery-powered systems to ensure consistent performance as the battery discharges.
• Industrial Control Systems: Supplying stable power to components in industrial control and automation equipment.
• Networking Equipment: Providing regulated power for network interface cards, routers, and switches.

Features

• Low Dropout Voltage: Operates with a low dropout voltage, allowing it to maintain regulation even when the input voltage is close to the output voltage.
• 3A Output Current: Capable of delivering up to 3A of output current, making it suitable for moderate power applications.
• 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 3.3V Output: Provides a stable and precise 3.3V output voltage.

Benefits

• High Efficiency: Minimizes power dissipation and heat generation, improving overall system efficiency.
• Reliable Operation: Provides a stable and reliable 3.3V supply, ensuring consistent operation of powered devices.
• Overload Protection: Protects against damage from overcurrent and overtemperature conditions.

Additional Details

The AMS1587CT-3.3 is available in a TO-220 package. For stable operation, it is recommended to use an output capacitor with a value between 10μF and 100μF, and a low ESR (Equivalent Series Resistance). 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. Proper layout techniques, such as keeping traces short and wide, are also recommended for optimal performance.
