78L12-LDO12V LINEAR VOLTAGE REGULATOR TO-92

The 78L12 is a three terminal voltage regulator. The three terminals are Input, Output and ground as shown in the 78L05 pinout diagram. It is very easy and straight forward to use this IC, just connect the input in to the input voltage which has to be regulated and the ground pin to system ground. The regulated 5V can be obtained from the output pin if the IC.

In the circuit below a input voltage of 12V is regulated to 5V using the 78L05. You use the 5V to power any small loads like LED which is rated for less than 100mA. Because the maximum current that this IC could supply is only upto 100mA.
