ADP7159

2 A, Ultralow Noise, High PSRR, Adjustable Output, RF Linear Regulator

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.

Applications

  • Regulation to noise sensitive applications: phase-locked loops (PLLs), voltage controlled oscillators (VCOs), and PLLs with integrated VCOs
  • Communications and infrastructure
  • Backhaul and microwave links

Product Details

The ADP7159CP-04-EVALZ and ADP7159RD-04-EVALZ evaluation boards demonstrate the operation and functionality of the ADP7159 ultralow noise, 2 A, adjustable output, radio frequency (RF) linear regulator.


Simple device measurements such as line and load regulation, dropout voltage and ground current can be demonstrated using only a single voltage supply, load resistors, and a voltmeter or an ammeter.


Complete specifications for the ADP7159 ultralow noise, 2 A, adjustable output, radio frequency (RF) linear regulator are available in the ADP7159 data sheet available from Analog Devices, Inc., and should be consulted in conjunction with user guide UG-811 when using the evaluation boards.
