ADP715x LDO Voltage Regulators Analog Devices Inc. ADP715x LDO (Low Dropout) Voltage Regulators operate from 2.3V to 5.5V and provide up to 2A of output current. Output voltages of 1.2V to 3.3V are possible depending on the model. The ADP715x uses an advanced proprietary architecture that provides high power supply rejection and ultralow noise. This architecture achieves excellent line and loads transient response with only a 10μF ceramic output capacitor. The ADP715x is available in four models that optimize power dissipation and PSRR performance as a function of the input and output voltage.
