The N78018-2CH is a non-isolated, 2A DC-DC switching regulator designed to provide a regulated 1.8V output. It operates over a wide input voltage range of 4.5V to 28V and features an efficiency of 83% at minimum input voltage and full load. This regulator is pin-out compatible with LM78xx linear regulators and includes built-in protections for short circuits, overload, and over-temperature conditions. It is designed to operate in a wide temperature range from -40°C to +85°C without an additional heatsink, making it suitable for various industrial applications. Common uses include point-of-load regulation, voltage step-down for industrial controls, and power for microcontroller-based systems.
