11 / 23 page HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.2.1_00 S-T111 Series Seiko Instruments Inc. 11 Operation 1. Basic operation Figure 11 shows the block diagram of the S-T111 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. Reference voltage circuit VOUT *1 *1. Parasitic diode VSS VIN Rs Rf Error amplifier Current supply Vref − + Vfb Figure 11 2. Output transistor The S-T111 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. |
