The circuit shown has a maximum output current of 1.5 A. We find this traditional configuration in the Linear Applications Handbook by National Semiconductor. R1 must be wire.
This circuit operates at the frequency of a small transmitter up to 27 MHz, triggering a relay from...
This medium wave radio with 7 germanium transistors was manufactured in Japan in the 1960s. Its...
In the figure we have the way to implement a power zener diode. The voltage depends on the zener,...
