Operation
1. Basic operation
Figure 17 shows the block diagram of S-1313 Series.
The error amplifier compares the reference voltage (Vref) with feedback voltage (Vfb), which is the output voltage
resistance-divided by feedback resistors (Rs and Rf). It supplies the gate voltage necessary to maintain the constant
output voltage which is not influenced by the input voltage and temperature change, to the output transistor.

2. Output transistor
In the S-1313 Series, a low on-resistance P-channel MOS FET is used 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.
