ADP7142 with 5 V Output Adjusted to 6 V GENERAL DESCRIPTION The ADP7142 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, low noise, and achieves excellent line and load transient response with a small 2.
2 µF ceramic output capacitor.
The ADP7142 regulator output noise is 11 μV rm...
