Three-terminal fixed voltage stabilized power supply circuit

The three-terminal voltage-stabilized power supply consists of a transformer T, a rectifier bridge VD1~VD4, a filter capacitor Ct and a j-terminal fixed voltage stabilizing integrated block.
The output voltage is fixed at 15V and cannot be adjusted, as shown in the figure.
    The input and output voltage and other parameters of different voltage stabilizing blocks are different
, so readers must pay attention when selecting them.
    The parameters of several different voltage stabilizing blocks are shown in the table.
