Operation
1. Basic Operation
2. Output Transistor
Figure 16 shows the block diagram of the S-812C Series.
The error amplifier compares the reference voltage (V
divided by feedback resistors R
output voltage which is not influenced by the input voltage and temperature change, to the output
transistor.
In the S-812C Series, a low on-resistance P-channel MOS FET is used as the output transistor.
