Hand Held Transceiver dc Adapter Circuit Diagram

This Hand Held Transceiver dc Adapter Circuit Diagram provides a regulated 9-V source for operating a Kenwood TR-2500 hand-held transceiver in the car. The LM317T`s mounting tab is electrically connected to its output pin, so take this into account as you construct your version of the adapter. The LM317T regulator dissipates 2 or 3 W in this application, so mount it on a 1-x -2-inch piece of `is-inch-thick aluminum heatsink.
