Description of Operation
1. Basic Operation
Figure 11
shows the block diagram of the S-818 Series.
The error amplifier compares a reference voltage (Vref) with the part of the output voltage divided by the
feedback resistors Rs and Rf. It supplies the output transistor with the gate voltage, necessary to ensure
certain output voltage free of any fluctuations of input voltage and temperature.

2. Output Transistor
The S-818 Series uses a Pch MOS FET as the output transistor.
Be sure that VOUT does not exceed VIN
+0.3 V to prevent the voltage regulator from being damaged due to
inverse current flowing from VOUT pin through a parasitic diode to VIN pin.
