Product Details

The ADP7156CP-3.3EVALZ evaluation board demonstrates the operation and functionality of the ADP7156 ultralow noise, 1.2 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 ADP7156 ultralow noise, 1.2 A, linear regulator are available in the ADP7156 data sheet available from Analog Devices, Inc., and should be consulted in conjunction with user guide UG-809 when using the evaluation board.
