With the development and availability of small LCD screens for automotive use, especially in conjunction with DVD players, many users have seen the possibility of also using them with video games, specifically with the PS2. However, this game does not have any accessories for its power supply in a car, and its operating voltage is 8.5 V, different from the car battery that provides 12 V. The simple circuit presented is then the solution, as it provides the voltage and current necessary for the perfect functioning of the game in this situation. The CI7808 stabilizes the voltage and polarizes the transistors so that they supply the game with the current necessary for its operation. Zen diodes protect the input and output of the circuit against over voltages. The connection to the car can be made at the outlet of the cigarette lighter.
