The AP2120 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. The AP2120 series feature high supply voltage 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 AP2120 series have 1.2V, 1.3V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.2V, 3.3V, 3.6V, 4.0V and 5.0V versions.
· Low Dropout Voltage at IOUT=100mA: 200mV Typical (Except 1.2V, 1.3V and 1.5V Versions) · Low Quiescent Current: 25μA Typical · High Ripple Rejection: 65dB Typical (F=1kHz) · Output Current: More Than 150mA (250mA Limit) · Extremely Low Noise: 15μVrms@VOUT=1.2V, 1.3V, 1.5V (10Hz to 100kHz) · Excellent Line Regulation: 4mV Typical · Excellent Load Regulation: 12mV Typical · High Output Voltage Accuracy: ±2% · Excellent Line Transient Response and Load Transient Response · Compatible with Low ESR Ceramic Capacitor (as Low as 1μF)
