Rochester Electronics PMIC - Voltage Regulators - DC DC Switching Regulators LM2575T-5G

The LM2575T-5G is a step-down switching regulator capable of delivering a fixed output voltage of 5.0 V at a maximum output current of 1.0 A. It operates efficiently within a wide input voltage range of 4.75 V to 40 V, making it suitable for various applications. The device features a guaranteed output voltage tolerance of ±4% under specified conditions and includes an internal oscillator with a fixed frequency of 52 kHz. This regulator is designed to minimize the number of external components required, simplifying the power supply design. It incorporates features such as thermal shutdown and cycle-by-cycle current limiting for enhanced protection. The LM2575T-5G is also AEC-Q100 qualified, making it suitable for automotive applications. Its low power standby mode and TTL shutdown capability contribute to its efficiency, while the moisture sensitivity level is rated at 1. The device is available in a TO-220 package, which facilitates heat dissipation without the need for a heatsink in many cases.
