Description
The HOPERF LM7812 is integrated linear positive regulator with three terminals. The LM7812 offer several fixed output voltages making them useful in wide range of applications. When used as a zener diode/resistor combination replacement, the LM7812 usually results in an effective output impedance improvement of two orders of magnitude, lower quiescent current. The LM7812 is available in the TO-220 packages.
