The AP2122 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 . The AP2122 series feature high ripple rejection, low dropout voltage, low noise, high output voltage accuracy, and low current consumption which make them ideal for use in various battery-powered devices. The AP2122 series have 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.2V and 3.3V versions.
· Low Dropout Voltage at IOUT=100mA: 150mV Typical (Except 1.5V Version) · Low Standby Current: 0.1μA Typical · Low Quiescent Current: 25μA Typical · High Ripple Rejection: 70dB Typical(F=10kHz) · Maximum Output Current: More Than 150mA (300mA Limit) · Extremely Low Noise: 30μVrms (10Hz to 100kHz) · Excellent Line Regulation: 4mV Typical · Excellent Load Regulation: 12mV Typical · High Output Voltage Accuracy: ±2% · Excellent Line and Load Transient Response · Compatible with Low ESR Ceramic Capacitor (as Low as 1μF)
