The LM2597M-5.0 is a buck switching regulator from Quarktwin Technology Ltd. designed to provide a fixed output voltage of 5V with a maximum output current of 500mA. It operates with an input voltage range of up to 60V and features a fixed switching frequency of 150 kHz, which allows for smaller filter components compared to lower frequency regulators. The device includes essential features such as thermal shutdown, current limit protection, and a shutdown/soft-start function to minimize inrush current during startup. The LM2597M-5.0 is available in an 8-pin SOIC package, making it suitable for space-constrained applications. Its high efficiency and low power standby mode (typically 85 OºA) enhance its usability in various applications, including as a preregulator for linear regulators and on-card switching regulators.
