The main purpose of this IC is to supply required regulated negative voltage to the circuits. IC 79xx can supply a constant negative voltage output, in spite of any voltage fluctuations in its input voltage. Voltage regulator IC can be defined as an integrated circuit that is capable of supplying a constant controlled output voltage which is not at all affected by the variations in input voltage provided that the variations are within the prescribed limits under specified atmospheric conditions.
Voltage fluctuations may damage or reduce the life of circuit components. Usage of voltage regulator ICs helps in avoiding such events by maintaining voltage at the required levels.
IC 79xx is a three pin negative voltage controller IC. It is a small integrated circuit used in a circuit to supply a constant negative input voltage. The number 79 indicates that it is a negative voltage regulator and xx indicates the output voltage of the IC.

Similarly if it isthen output voltage of the IC is volts and so on. IC 79xx requires heat sink for its safe operation. Heat sink boosts heat dissipation therefore the life of the device can be extended. IC 79xx is used in circuits as shown in the circuit. In order to improve stability two capacitors — C 1 and C 2 are used. The capacitor C 1 is used only if the regulator is separated from filter capacitor by more than 3″. It must be a 2. The capacitor C 2 is required for stability.
Values given may be increased without limit. The maximum value of input voltage that the IC can withstand is 24 volts. Sign in or sign up and post using a HubPages Network account. Comments are not for promoting your articles or other sites.
