ADPL44002AUJZ-1.8-R7

A CMOS, low dropout (LDO) linear regulator that operates from 2.7V to 40V and provides up to 200mA of output current. 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 regulator output noise is 20μVRMS independent of the output voltage for the fixed options of 5V or less. Available in four fixed output voltage options: 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. User programmable soft start with an external capacitor is available in the LFCSP package. Available in a 6-lead, 2mm×2mm LFCSP and a 5-lead TSOT.
