Found in documentation from the 1990s, this circuit converts 12 V to 9 V from a car's power output. The 100mA current eliminates the need for a heatsink on the transistor.
By polarizing the reference with the supply voltage we can use these amplifiers in logic circuits....
The circuit we present was found in an English magazine from 1973. The complementary pair of power...
Found in an American documentation from 1969, this circuit operates at a frequency determined by the...
