Operation
2. Output transistor
1. Basic operation
Figure 11 shows the block diagram of the S-T111 Series.
The error amplifier compares the reference voltage (V
divided by feedback resistors R
to ensure a certain output voltage free of any fluctuations of input voltage and temperature.
The S-T111 Series uses a low on-resistance P-channel MOS FET as the output transistor.
Be sure that V
to inverse current flowing from the VOUT pin through a parasitic diode to the VIN pin.
