LM78L05 - 5V Positive Voltage Regulator
This is a member of a series of three terminal positive regulators which are available in the TO-220 package and with several fixed output voltages, making them useful in a wide range of applications. They provide a constant output voltage for a varied input voltage. In our case the 78L05 IC is an iconic regulator IC that finds its application in most of the projects. The name 78L05 signifies two meaning, “78” means that it is a positive voltage regulator and “05” means that it provides 5V as output. So our 7805 will provide a +5V output voltage. The output current of this IC can go up to 100mA. But, the IC suffers from heavy heat loss hence a Heat sink is recommended for projects that consume more current. For example if the input voltage is 12V and you are consuming 50mA, then (12-5) * (50*10^-3) = 0.35W. This 0.35 Watts will be dissipated as heat.
