ADP7142ARDZ-5.0-R7 Description
The ADP7142ARDZ-5.0-R7 is a CMOS, low dropout (LDO) linear regulator that operates from 2.7 V to 40 V and provides up to 200 mA of output current.
This high input voltage LDO is ideal for the regulation of high-performance analog and mixed-signal circuits operating from 39 V down to 1.2 V rails.
Using an advanced proprietary architecture, the device provides high power supply rejection, and low noise, and achieves excellent line and load transient
response with a small 2.2 µF ceramic output capacitor. The ADP7142ARDZ-5.0-R7 regulator output noise is 11 μV rms independent of the output voltage for
the fixed options of 5 V or less.
