LM2575SX-5.0 Description

Short technical summary and product information.

The Texas Instruments LM2575SX-5.0 is a monolithic integrated circuit designed as a step-down (buck) switching regulator. It is capable of driving a 1A load with excellent line and load regulation. This specific device provides a fixed 5V output voltage.

 

Key electrical specifications include a 1A output current, a 52kHz fixed switching frequency, and a wide input voltage range. The operating temperature range is -40°C to 125°C (TJ). The regulator requires only a few external components to function, simplifying circuit design.

 

This component is housed in a TO-263-6, D²Pak (5 Leads + Tab), TO-263BA package and is designed for surface mount applications. The package quantity is typically 500 units on a tape and reel.

 

The LM2575 series offers features such as TTL shutdown capability for low power standby mode, high efficiency, and built-in thermal shutdown and current limit protection, making it suitable for various power management applications.
