This high input voltage LDO is ideal for the regulation of high performance analog and mixed signal circuits operating from 39V down to 1.2V rails. Using an advanced proprietary architecture, the device provides high power supply rejection, low noise, and achieves excellent line and load transient response with a small 2.2µF ceramic output capacitor. The ADPL44002 regulator output noise is 20μVRMS independent of the output voltage for the fixed options of 5V or less. The ADPL44002 is available in four fixed output voltage options. The following voltages are available from stock: 1.2V (adjustable), 1.8V, 2.5V, 3.3V, and 5.0V. Each fixed output voltage can be adjusted above the initial set point with an external feedback divider. This allows the ADPL44002 to provide an output voltage from 1.2V to VIN - VDO with high PSRR and low noise. User...
