The N78025-2C is a non-isolated DC-DC switching regulator designed to provide a regulated -2.5V output at up to 1000mA. It operates from a wide input voltage range of 8V to 32V with a high efficiency of 86%, often eliminating the need for an external heatsink. This device is pin-out compatible with LM79xx series linear regulators, serving as a high-efficiency upgrade. Key features include built-in short circuit, overload, and over-temperature protections, and a wide operating temperature range, making it suitable for industrial PCs, data communications, and point-of-load regulation in distributed power systems.
