Communications and infrastructure
Backhaul and microwave links GENERAL DESCRIPTION
The ADP7159 is an adjustable linear regulator that operates from
2.3 V to 5.5 V and provides up to 2 A of output current. Output
voltages from 1.2 V to 3.3 V are possible depending on the model.
Using an advanced proprietary architecture, the device provides
high power supply rejection and ultralow noise, achieving excellent
line and load transient response with only a 10 μF ceramic
output capacitor.
The ADP7159 is available in four models that optimize power
dissipation and PSRR performance as a function of the input
and output voltage. See Table 9 and Table 10 for selection guides.
The typical output noise of the ADP7159 regulator is 0.9 μV rms
from 100 Hz to 100 kHz and 1.7 nV/√Hz for noise spectral density
from 10 kHz to 1 MHz. The ADP7159 is available in 10-lead,
3 mm × 3 mm LFCSP and 8-lead SOIC packages, making it not
only a very compact solution, but also providing excellent thermal …
