Additional Details

The KA7818 is a linear voltage regulator that provides a stable 18V output. It requires minimal external components for operation. The internal thermal overload protection shuts down the regulator when the junction temperature exceeds a safe limit, preventing damage. The short circuit current limiting protects the regulator from excessive current draw. It is typically available in a TO-220 package.
