Operation
*1. Parasitic diode
Figure 12 shows the block diagram of the S-818 Series.
The error amplifier compares a reference voltage (V
feedback resistors R
certain output voltage free of any fluctuations of input voltage and temperature.
The S-818 Series uses a Pch MOS FET as the output transistor.
