7.2 V to 12.0 V
Reference Voltage
HA12231FP provides the reference voltage of half the supply voltage that is the signal grounds. As the
peculiarity of this device, the capacitor for the ripple filter is very small about 1/100 compared with their
usual value. The block diagram is shown as figure 1.
