## Description

The LM2575HVS-12 from Texas Instruments is a versatile step-down (buck) switching regulator IC. It is designed to provide a fixed 12V output voltage and is capable of driving a 1A load with excellent line and load regulation. This device operates at a fixed switching frequency of 150 kHz, allowing for the use of smaller filter components compared to lower-frequency regulators.

Requiring a minimum number of external components, the LM2575HVS-12 is simple to use and includes internal frequency compensation and a fixed-frequency oscillator. It features a guaranteed ±4% tolerance on output voltage under specified input voltage and output load conditions. The device also includes external shutdown capability and self-protection features such as thermal shutdown and current limit protection.

This regulator is available in a TO-263-5 surface mount package, making it suitable for various electronic designs. Its input voltage range is up to 40V, and it operates within a junction temperature range of -40°C to 125°C.
