HIGH RIPPLE-REJECTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR

S-1112/1122 Series

Rev.5.0_00

Seiko Instruments Inc.

Operation

1. Basic operation

Figure 12 shows the block diagram of the S-1112/1122 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-1112/1122 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 VOUT pin through a parasitic diode to VIN pin.
