AP2121 Overview
Features Data Sheet AP2121 The AP2121 series are positive voltage regulator ICs fabricated by CMOS process. Each of these ICs consists of a voltage reference, an error amplifier, a resistor network for setting output voltage, a current limit circuit for current protection and a chip-enable circuit (5-pin products only). The AP2121 series feature high supply voltage ripple rejection, low dropout voltage, low noise,...
