ADP7159ACPZ-04-R7

LDO Regulator Pos 1.2V to 3.3V 2A 10Pin LFCSP T/R

Product Details

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.

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 performance for applications requiring up to 2 A of output current in a small, low profile footprint.
