Description of Operation
1. Basic Operation
Figure 15 shows the block diagram of the S-812C series. The error amplifier compares a reference
voltage (Vref) with a part of the output voltage divided by the feedback resistors Rs and Rf, and supplies
the gate voltage to the output transistor, necessary to ensure certain output voltage independent from
change of input voltage and temperature.

2. Output Transistor
The S-812C Series uses a Pch MOS FET as the output transistor.
The voltage at VOUT must not exceed VIN+0.3V. When the VOUT voltage becomes higher than that of VIN,
reverse current flows and may break the regulator since a parasitic diode between VOUT and VIN pins
exists inevitably.
