Regulator adjustment circuit

Regulator has the following components: 1, adjusting circuit; 2, the sampling circuit; 3, sampling amplification; 4, the reference circuit;
Regulation process: Let the output Voltage stabilizer has reached the preset voltage. When the output voltage changes, the sampling circuit is amplified and sampled to obtain a sample of comparative judgment reference circuit air circuit breaker is changed to high or to low a change, and to determine the amount of change, thereby controlling the adjustment circuit, adjusting the output voltage adjusting circuit to promote the changes in low or high until the output reaches the preset voltage.
