The AZ70XX arean error amplifier, a resistor network
for setting output voltage, a current limit circuit for cur-
monitor power supplies.

only).
The AZ70XX use a precision on-chip voltage reference
and a comparator to measure the input operating voltage.
The AP2121 series feature high ripple rejection, detecting
These ICs can accurately reset the system after low drop-
