Operation
2. Output transistor
1. Basic operation
Figure 13 shows the block diagram of the S-1132 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-1132 Series uses a low on-resistance P-channel MOS FET as the output transistor.
Be sure that V
