Q. Draw the complete circuit of a dual voltage source using 7805 and 7905.
A voltage regulator is a circuit that supplies a constant voltage regardless of changes in load currents. Although voltage regulators can be designed using op-amps, it is quicker and easy to use IC voltage regulators. Furthermore, IC voltage regulators are versatile and relatively inexpensive and are available with features such as a programmable output, current/voltage boosting, thermal shutdown and floating operation for high voltage applications. IC voltage regulators are of the following types
1. Fixed Output Voltage Regulators
a. Positive Voltage Regulators - IC 7800 Series
b. Negative Voltage Regulators - IC 7900 Series
2. Adjustable Output Voltage Regulators
a. Positive Voltage Regulators - IC LM317 Series
b. Negative Voltage Regulators - IC LM337 Series
Voltage regulators are commonly used for on-card regulation and laboratory-type power supplies.
