This power supply may have 5, 6, 9 or 12 V outputs depending on the 78XX and 79XX series regulators used. The transformer shall have a secondary voltage 2 V higher than that required at the output and a current of 1 A. The integrated circuits shall be fitted with heat radiators. Note that the pinout of the regulators 78 is different from the regulators 79. The circuit is from the book Robotics, Mechatronics and Artificial Intelligence of Newton C. Braga published in the United States.
