7918 -18V Negative Voltage Regulator IC

7912 designed as negative voltage regulators supplying a negative voltage of 18V. These regulator ICs offer very acceptable levels of performance for a wide range of applications. And additionally, to the present, these IC available at an affordable rate and quite easy to use. 79xx voltage regulators are very commonly utilized in electronic circuits. the most purpose of this IC is to provide the required regulated negative voltage to the circuits. IC 79xx can supply a continuing negative voltage output, in spite of any voltage fluctuations in its input voltage. These IC often mainly found within the circuits during which integrated circuits that need +Vcc and – Vcc  used.

IC 79xx maybe a three-pin negative voltage controller IC. These IC designed as a integrated circuit utilized in a circuit to provide a continuing negative input voltage. the amount 79 indicates that it’s a negative transformer and xx indicates the output voltage of the IC. ‘xx’ are often replaced by the controlled output voltage provided by the regulator, for instance, if it’s 7905, then the output voltage of the IC is -5 V. Similarly if it’s 7912, then output voltage of the IC is -12 volts then on. The name of the IC may vary supported by the manufacturer as LM79xx, L79xx, MC79xx etc.IC 79xx requires heat sink for its safe operation. Heat sink boosts heat dissipation therefore the life of the device can be extended.
