This high current regulator with low voltage drop was found in the datasheet of the used integrated circuit itself. The transistor accepts an equivalent and must be provided with a heat sink.
This circuit was obtained in a 1960 transistor manual from Sylvania. The circuit uses small...
This 1980s documentation circuit uses a 741 in a different high-speed comparator configuration. The feed...
This is the typical circuit of a 60's tape recorder. The circuit uses only two transistors and has a...
