Operation
1. Basic Operation
2. Output Transistor
ULTRA LOW CURRENT CONSUMPTION, HIGH RIPPLE REJECTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR
Figure 12 shows the block diagram of the S-1167 Series.
The error amplifier compares the reference voltage (V
feedback resistors R
output voltage free of any fluctuations of input voltage and temperature.
The S-1167 Series uses a low on-resistance P-channel MOS FET as the output transistor.
