The heat sink prevents our regulator ic from overheating and short-circuits. It has a heat-sink with the common ground connected with it. Farnell offers fast quotes, same day dispatch, fast delivery, wide inventory, datasheets & technical support. The 7812 ic has a built-in protection from the high current. Buy 7812 - 78M12 - SMD TO-252/DPAK Package - 12V Positive Voltage Regulator IC online in India at best price and high quality only on . Buy L7812CV - Stmicroelectronics - Linear Voltage Regulator, 7812, Fixed, Positive, 19V To 35V In, 12V And 1.5A Out, TO-220-3.
7812 voltage regulator ic does not require any component to balance or saturate their output voltage.You can use the capacitors in order to minimize the voltage fluctuations in the circuit and maintains the constant voltage across the input as well as output of the circuit.Īlso see difference between microprocessor and microcontroller. Reverse polarity does get the ic heat up really quickly, you can also use a pn junction diode in order to prevent such a condition. You also have to be careful with the connection you are making with the voltage supply. When using the voltage regulator setup, you need to take care of the current through the voltage regulator ic do not exceed beyond the capacity which is mentioned in the datasheet or else it may blow off. ELECTRICAL CHARACTERISTICS FOR L7812 (refer to the test circuits. The Pin 2 is common between both input as well as output voltage. fixed voltage regulators, these devices can be.
