onsemi Voltage Regulators - DC DC Switching Regulators LM2575TV-005G

The LM2575TV-005G is a step-down switching regulator capable of delivering a fixed output voltage of 5V at a maximum load of 1.0 A. It operates within a wide input voltage range of 4.75 V to 40 V, making it suitable for various applications. The device features high efficiency, particularly when compared to linear regulators, which helps minimize power dissipation and often eliminates the need for a heatsink. This regulator is designed to simplify power supply design by requiring only four external components. It includes features such as thermal shutdown and cycle-by-cycle current limiting for protection under fault conditions. The LM2575TV-005G also supports TTL shutdown capability, allowing for low power standby operation. With a guaranteed output voltage tolerance of ±4% and an internal oscillator frequency of 52 kHz, it provides reliable performance across specified conditions. The LM2575 series is AEC-Q100 qualified, making it suitable for automotive applications. The device is available in a TO-220 package, which facilitates easy integration into various circuit designs.
