Product details
Voltage sources in a circuit may have fluctuations resulting in not providing fixed voltage outputs. A voltage regulator IC maintains the output voltage at a constant value. 7812 Voltage Regulator, a member of the 78xx series of fixed linear voltage regulators used to maintain such fluctuations, is a popular voltage regulator integrated circuit (IC).
The xx in 78xx indicates the output voltage it provides. 7812 IC provides +12 volts regulated power supply with provisions to add a heat sink.
