Description

The SPX1587AR is a 5A Low Dropout (LDO) positive voltage regulator manufactured by Sipex Corporation (later acquired by Exar, now part of Renesas). This regulator is designed to provide a stable output voltage with low dropout voltage, making it suitable for applications where the input voltage is close to the desired output voltage. The SPX1587AR is commonly used in power supplies, battery chargers, and other voltage regulation circuits.

Applications

  • Power supplies
  • Battery chargers
  • Post regulation for switching power supplies
  • Linear regulators
  • Motherboard power regulation

Features

  • 5A output current capability
  • Low dropout voltage (typically less than 1.3V at 5A)
  • Adjustable output voltage
  • Overcurrent and overtemperature protection
  • Reverse battery protection
  • Fixed output voltage options available

Benefits

  • Provides a stable output voltage even with low input voltage
  • High output current capability for demanding applications
  • Adjustable output voltage for design flexibility
  • Protects the regulator and load from damage
  • Prevents damage from reversed battery connections

Technical Specifications

The SPX1587AR can provide up to 5A of output current with a typical dropout voltage of less than 1.3V at full load. The output voltage can be adjusted using external resistors. The regulator includes overcurrent and overtemperature protection to prevent damage from overload conditions. The SPX1587AR is available in various packages, such as TO-220 and TO-263. Refer to the Renesas (formerly Sipex/Exar) datasheet for detailed specifications, including input voltage range, output voltage accuracy, and thermal characteristics.

The SPX1587AR is a reliable and versatile LDO regulator suitable for a wide range of applications requiring stable voltage regulation and high output current capability. Its low dropout voltage and protection features make it an ideal choice for battery-powered devices and other applications where efficiency and reliability are critical. Always consult the manufacturer's datasheet for detailed specifications and application guidelines.
