How do you protect a voltage regulator?
How do you protect a voltage regulator? If the output voltage of the regulator is more than 7 V higher than the input voltage, the emitter-base junction of the internal power transistor can break down and cause the transistor to fail. You can use a shunt diode to prevent this condition (see Figure 2). How do you protect an electronic circuit from overvoltage? In order to protect the circuit from overvoltage conditions, Zener diodes are often the first option. A Zener diode follows the same diode theory, which blocks the current flow in the reverse direction. What are various protection...
