WHAT IS A VOLTAGE REGULATOR
• A voltage regulator is a circuit that supplies a constant voltage regardless of changes in load currents.
• Although VR can be designed using op-amps, it is easier and quicker to use IC regulators
• IC regulators are used because they are: Versatile Relatively inexpensive Features like programmable output Internal short-circuit current limiting Thermal shutdown etc.

TYPES OF VOLTAGE REGULATOR
• Fixed output voltage regulator• Adjustable output voltage regulator• Switching regulator• Special regulator• Except for the switching regulators, all other
types of voltage regulators are linear regulators

78XX AND 79XX IC

78XX AND 79XX IC
• When specifying individual ICs within this family, the xx is replaced with a two-digit number, which indicates the output voltage the particular device is designed to provide (for example, the 7805 has a 5 volt output, while the 7812 produces 12 volts). The 78xx line are positive voltage regulators, meaning that they are designed to produce a voltage that is positive relative to a common ground. There is a related line of 79xx devices which are complementary negative voltage regulators. 78xx and 79xx ICs can be used in combination to provide both positive and negative supply voltages in the same circuit, if necessary.
