HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR

Operation
1. Basic operation
Figure 13 shows the block diagram of the S-1132 Series.
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.

2. Output transistor
The S-1132 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.
