Product Brief VOLTAGE HIGH SPEED, DETECTOR EXTREMELY LOW NOISE LDO REGULATOR Description AZ70XX AP2121 Parametric Table The AP2121 positive voltage regulator ICs with fabAZ70XXseries seriesare ICs are under voltage detectors ricated by CMOS process. Each of these ICs consists of a a built in voltage threshold and low power consumption. voltage reference, an error amplifier, a resistor network The AZ70XX are specifically designed to accurately for setting output voltage, a current limit circuit for curmonitor power supplies. rent protection and a chip enable circuit (5-pin products only). The AZ70XX use a precision on-chip voltage reference and a comparator to measure the input operating voltage. The AP2121 series featurereset high the ripple rejection, dropThese ICs can accurately system after low detecting out voltage, low noise, high output voltage accuracy, and voltage at the time of switching power on and instantalow current consumption which make them ideal for use neous power off in various CPU systems and other logic in various battery-powered devices. systems. The detect voltage thresholds are 2.3V/2.5V/ 2.7V/2.9V/3.1V/3.3V/4.2V/4.5V for AZ7023/25/27/29/ The AP2121respectively. series have Built 1.5V,in1.8V, 2.5V,helps 2.8V,to3.0V, 31/33/42/45 hysteresis pre3.2V and 3.3V versions. vent erratic operation in the presence of noise. The AP2121 are available in standard SOT-23-3 and SOTFeatures 23-5 packages.
