The SPX1086T-2.5 is a low dropout (LDO) positive voltage regulator from Sipex Corporation, pre-set to provide a stable 2.5V output. It is designed for applications requiring a regulated voltage source, even when the input voltage is only slightly higher than the output voltage.

Applications:

• Microcontroller Power: Supplies stable 2.5V power for microcontrollers.
• Digital Logic Circuits: Regulates voltage for various digital logic components.
• Post Regulation for Switching Supplies: Used to filter noise and improve stability after a switching regulator.
• Battery-Powered Devices: Ideal for maintaining 2.5V in battery-operated devices.
• FPGA Power Rails: Provides the required 2.5V voltage for FPGA core or I/O.

Features:

• Fixed 2.5V Output: Provides a precise and stable 2.5V output voltage.
• Low Dropout Voltage: Operates with minimal input-output voltage differential.
• Current Limiting: Protects the regulator and the load from overcurrent faults.
• Thermal Shutdown: Shuts down the regulator in case of overheating to prevent damage.
• Reverse Battery Protection: Prevents damage if the battery is connected in reverse polarity.

Benefits:

• Stable 2.5V Supply: Guarantees consistent power to sensitive circuits.
• Efficient Power Conversion: Low dropout minimizes power loss.
• Enhanced Reliability: Protection features enhance the lifespan of the regulator and connected devices.
• Simplified Design: Requires few external components for operation.
