The ADP7159ACPZ-01-R7 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 excellentline and load transient response with only a 10 μF ceramicoutput capacitor.
The ADP7159ACPZ-01-R7 is available in four models that optimize powerdissipation and PSRR performance as a function of the inputand output voltage.
The typical output noise of the ADP7159ACPZ-01-R7 regulator is 0.9 μV rmsfrom 100 Hz to 100 kHz and 1.7 nV/√Hz for noise spectral densityfrom 10 kHz to 1 MHz. The ADP7159ACPZ-01-R7 is available in 10-lead,3 mm × 3 mm LFCSP and 8-lead SOIC packages, making it notonly a very compact solution, but also providing excellent thermal performance for applications requiring up to 2 A of outputcurrent in a small, low profile footprint.
