Three-terminal Positive Regulator

There are two main types of three-terminal voltage stabilizer. One is fixed output voltage, called fixed output three-terminal voltage stabilizer, and the other is adjustable output voltage, called adjustable output three-terminal voltage stabilizer. Its basic principle is the same, and all adopt series voltage stabilizer circuit. In the linear integrated voltage regulator, because the three-terminal voltage regulator has only three outgoing terminals, it has the advantages of less external components, convenient use, stable performance, low price, and so on, so it is widely used.
