Description
Description
The AP2127 Series are positive Voltage regulator ICs
The AZ70XX series ICs are under voltage detectors with
fabricated by CMOS process.
a built in voltage threshold and low power consumption.
The AZ70XX are specifically designed to accurately
monitor power supplies.
The AP2127 Series have features of low dropout voltage,
low noise, high output voltage accuracy, and low current
The AZ70XX use a precision on-chip voltage reference
consumption which make them ideal for use in various
and a comparator to measure the input operating voltage.

These ICs can accurately reset the system after detecting
voltage at the time of switching power on and instanta-
AP2127 has 1.0V and 1.2V fixed voltage version.
