Operation
Regulator block
1. Basic operation
Figure 34 shows the block diagram of the regulator block.
The error amplifier compares the reference voltage (Vref) with Vfb, which is the output voltage resistance divided by
feedback resistors Rs and Rf. It supplies the output transistor with the gate voltage necessary to ensure a certain
output voltage free of any fluctuations of input voltage and temperature.
Output voltage is selectable from the range of 1.5 to 5.0 V in the S-1701 Series.

2. Output transistor
The S-1701 Series uses a low on-resistance P-channel 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 the VOUT pin through a parasitic diode to the VIN pin.
