ADPL44002AUJZ-1.8-R7

ADPL44002AUJZ-1.8-R7 is a CMOS, low-noise, low-dropout (LDO) linear regulator. This high-input-voltage LDO is ideal for the regulation of high-performance analogue 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. Applications include regulation to noise-sensitive applications (ADC, DAC circuits, precision amplifiers, power for VCO VTUNE control), communications and infrastructure, medical and healthcare, industrial and instrumentation.
