Technical Specifications

The SPX1584AT-5.0 has a low dropout voltage, typically less than 1.3V at the full rated output current of 7A. The input voltage range is typically between 4.75V and 7V. It provides a fixed output voltage of 5V with high accuracy. The regulator features overcurrent and overtemperature protection to prevent damage under fault conditions. The package is typically a TO-220, allowing for efficient heat dissipation. The operating temperature range is typically between -40°C and +125°C.

This low dropout regulator is ideal for applications where a stable and regulated 5V output voltage is required from a higher input voltage. Its low dropout voltage allows it to operate efficiently even when the input voltage is close to the output voltage. The high output current capability makes it suitable for powering demanding loads. The overcurrent and overtemperature protection features ensure safe and reliable operation. The SPX1584AT-5.0 is a reliable and efficient solution for a wide range of power supply applications.
