The SPX1587T-2.5 is a low dropout (LDO) linear regulator from Sipex Corporation. It is designed to provide a stable and regulated 2.5V output voltage from a higher input voltage, with minimal voltage drop across the regulator. This makes it suitable for applications where input voltage is close to the desired output voltage, such as battery-powered devices or systems with tight voltage tolerances.

Applications:

• Battery-powered systems
• Post-regulation for switching power supplies
• Microprocessor and microcontroller power supplies
• Portable electronics
• Linear regulation in noise-sensitive applications

Features:

• Low Dropout Voltage
• 2.5V Fixed Output Voltage
• 1.5A Output Current Capability
• Overcurrent and Overtemperature Protection
• Stable with Ceramic Output Capacitors
• Available in TO-220 and TO-263 Packages

Benefits:

• Efficient Power Regulation: Low dropout voltage allows for efficient regulation, even when the input voltage is close to the output voltage.
• Stable Output: Provides a stable and regulated 2.5V output voltage for sensitive electronic components.
• High Output Current: Capable of supplying up to 1.5A of output current for demanding applications.
• Robust Protection: Overcurrent and overtemperature protection features enhance the reliability of the regulator and the connected load.
• Ease of Use: Stable with ceramic output capacitors, simplifying circuit design and reducing component count.

The SPX1587T-2.5 is characterized by its low dropout voltage, which is typically less than 1V at the full rated output current of 1.5A. It operates with an input voltage range typically from 2.7V to 10V. The regulator is designed to be stable with ceramic output capacitors, which are commonly used in modern electronic devices due to their small size and low ESR (Equivalent Series Resistance). The overcurrent and overtemperature protection features safeguard the regulator and the load from damage due to excessive current draw or overheating. The device is typically available in TO-220 and TO-263 packages, offering options for through-hole and surface-mount assembly. It is often used as a post-regulator for switching power supplies to provide a clean and stable output voltage for sensitive components such as microprocessors and microcontrollers.
