Simple voltage stabilizer with high factor of stabilization

Despite relative simplicity, this stabilizer has very high factor of stabilization at a loading current др 0,5 A.Dostignuto it at the expense of the actual application in it two stabilizers - consecutive and parallel. The minimum power failure on a regulating element - 1,2В, and the maximum current of loading is defined by an initial current of a drain of the field VT1 transistor, and factor of strengthening of the VT2 transistor and can reach 0,5... 0,8А.
