MD7540 High Input CMOS Voltage Regulator

of Operation 1.Basic Operation Figure 8 shows the block diagram of the MD75XXH 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 a.
