This crowbar protection circuit for non-regulators blows the fuse when the load voltage exceeds a certain value. The configuration with component values can be seen in the previous circuit.
This circuit is from the 1974 Motorola Unijunction Trigger Circuits for Gated Thyristor. The triac...
Found in old American documentation, this circuit can divide the frequency of a signal by 2 or 3...
This transceiver is also low power, but this time, it can generate signals in the 144 MHz band. In the...
