1.2 A, Ultralow Noise, High PSRR, Adjustable Output, RF Linear Regulator
The ADP7157 is an adjustable linear regulator that operates from 2.3 V to 5.5 V and provides up to 1.2 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 ADP7157 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 the ADP7157 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 ADP7157 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 1.2 A of output current in a small, low profile footprint.

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
The ADP7157CP-04-EVALZ evaluation board demonstrates the operation and functionality of the ADP7157 ultralow noise, 1.2 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 ADP7157 ultralow noise, 1.2 A, adjustable output, radio frequency (RF) linear regulator are available in the ADP7157 data sheet available from Analog Devices, Inc., and should be consulted in conjunction with user guide UG-810 when using the evaluation board.
