The ADP7158 is a linear regulator that operates from 2.3 V to 5.5 V and provides up to 2 A of output current. Using an advanced proprietary architecture, it provides high power supply rejection and ultralow noise, achieving excellent line and load transient response with only a 10 µF ceramic output capacitor.

There are 16 standard output voltages for the ADP7158. The following voltages are available from stock: 1.2 V, 1.8 V, 2.0 V, 2.5 V, 2.8 V, 3.0 V, and 3.3 V. Additional voltages available by special order are 1.3 V, 1.5 V, 1.6 V, 2.2 V, 2.6 V, 2.7 V, 2.9 V, 3.1 V, and 3.2 V.

The ADP7158 regulator typical output noise 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 ADP7158 is available in a 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 Detail

The ADP7158CP-3.3EVALZ evaluation board demonstrates the operation and functionality of the ADP7158 ultralow noise, 2 A, fixed 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 ADP7158 ultralow noise, 2 A, linear regulator are available in the ADP7158 data sheet available from Analog Devices, Inc., and should be consulted in conjunction with user guide UG-794 when using the evaluation board.
