The EZ1583CM-2.5 is a 3A low dropout (LDO) linear regulator manufactured by Semtech Corporation. It is designed to provide a stable 2.5V output voltage and can deliver up to 3A of current. This regulator is ideal for applications requiring a well-regulated voltage supply with a minimal voltage drop, even at high current levels.

Applications:

• Microprocessor Power Supplies
• Post Regulators for Switching Supplies
• Constant Current Source
• Battery Powered Systems
• Hard Disk Drives

Features:

• 2.5V Fixed Output Voltage: Provides a stable and accurate 2.5V supply.
• 3A Output Current: Delivers ample current for demanding applications.
• Low Dropout Voltage: Maintains regulation with a minimal difference between input and output voltage.
• Overcurrent Protection: Prevents damage from excessive current draw.
• Thermal Overload Protection: Protects the regulator from overheating.
• Stable with Ceramic Capacitors: Allows for use of small, low-ESR ceramic capacitors.

Benefits:

• Stable Voltage Supply: Ensures consistent performance of connected devices.
• High Current Capability: Powers a wide range of loads.
• High Efficiency: Minimizes power loss and heat generation.

Additional Details:

The EZ1583CM-2.5 is typically packaged in a TO-263 package, which provides good thermal performance. Input and output capacitors are required for stable operation; refer to the datasheet for recommended capacitor values and types. Due to the high current capability, proper thermal management is essential to prevent overheating and ensure reliable operation. A heat sink may be necessary depending on the input voltage, output current, and ambient temperature.
