Voltage Regulators
Voltage regulators are commercially available as integrated circuits.
They stabilize voltages and compensate fluctuations...
Thereby voltage regulator can be
distinguished by their field of application...
-
Fixed Output Voltage Regulators
for different voltages (eg 7805, 7809),
-
adjustable voltage regulator (eg LM317),
-
voltage regulators with low power dissipation (eg LM2940),
-
High power voltage regulators for high currents, etc....
In the experiments, you use the following voltage regulator...
