Operation
1. Basic operation
2. Output transistor
Figure 23 shows the block diagram of the S-1711 Series.
The error amplifier compares the reference voltage (V
feedback resistors R
output voltage free of any fluctuations of input voltage and temperature.
The S-1711 Series uses a low on-resistance P-channel MOS FET as the output transistor.
Be sure that V
